from what huff from vivid told me....from midrange the 8 on average produced 12hp to the wheels...at top end it peaked at 19 to the wheel...check his sight for any diagrams...was i more clear this time?

nice keep updating... good one - it will be one of my definite mod

bob and xdeed - From what I understand the B&B exhaust which claims the 19hp your speaking of, is WITH the midpipe AND exhaust NOT just with the exhaust only.

Just a FYI for the sticky.

With the info above I have narrowed down to the B&B or Borla. Thanks again for collecting all the data.

this is a great thread
exhaust is my next upgrade

Looks awesome Bob! :D

Jason, You're right, I can't beat that! I left you a v-mail on your cell Sat. afternoon. Let's get a day that it isn't snowing and I'll be over. PM or call me and we'll get it put on.

I have just updated the Spintech info (see first post in this thread).

Hi guys,

I know you are proliferated with options of what is available in the USA.

I was merely asking to what "the quiet one" referred.
Are you asking about an aftermarket exhaust that is quieter than stock? To my knowledge all the aftermarket exhausts available for the RX-8 (other than something custom made to be extremely quiet) are louder than stock. Mine is probably the quietest of the bunch.

Thanks Bob,
That is what I was looking for......the quietest of the bunch.
You did do a nice job.

I have a custom system made by Spintech in Riverside, Calif.
They will be making it as a regular production model.
I think it is quieter than the other aftermarket systems, but a little louder than stock with a different tone.
I am awaiting a call from Spintech to do some dyno tests.

what you think about the mazda speed exhaust?
it is good exhaust?
i m intrested in e gredy or a hks but im lookin for a mazda speed exhaust just for dont loos the garanti

MazdaSpeed exhaust is basically a stock exhaust with the mazdaspeed logo on the tips that is all

i was looking at getting the greddy w/ midpipe...how do the ppl that actually have it feel towards it? etc

I just wanted to post a couple of video clips that I took of my 8 getting some dyno time after the installation of my RX8Store Exhaust. They were originally digital video that I transferred into an mpeg, so the video quality isn't the greatest but you'll enjoy the sounds I'm sure.

Jason & Xavier from the RX8Store as well as Sea Ray (all the way from Kentucky) were there for the fun. Special thanks to RX-8Freehk who put these into a format that the forum would take. There is one more video that is still trying to make it's way back from Germany where Freehk is at but enjoy these for now.

great posts everyone. this was alot of help for me, bobclevenger. thank you for spending the time man. this was alot easier than trying to find all the clips through various websites. the work was done already :D . thanks again

Hey guys< I am about to order the Borla system. It appears to me for cost $600 roughly and performance which is a supposed 12hp gain I read in another post it make sense. The fact that borla exhaust sounds deep and throaty I love the idea. Please can anyon etell me otherwise? Chime in please!

I would be very dubious of any catback system that claims 12HP! There is honestly not that much there to be gained.

BTW - Here is a pic of the recent Rotary Engine Track Day:

http://rx8.hymee.com/images/wakefield2004/Dscn5707.jpg

There are 7 RX-8's in the photo, and 4 of them have the my Hymee Enhanced "Cat Back".

We measured one of these at an honest 2kW which is about 3HP. That is in-line with what Racing Beat claim for theirs.

Cheers,
Hymee.

thanks for the clips Hymee. Exhaust sounds great

What about Mazdaspeed's exhaust? What are the specs on that? Which is exhaust sounds good and loud when you step on it but isn't always overbearingm someone mentioned to me HKS ?

Any information on the weight of all the currently available aftermarket exhaust system. Thanks

The shipped weight of the Hymee system is 17kg. So take off a few kilograms for the big carton and all the bubble wrap.

The Mazdaspeed exhaust is VERY quiet. As I've stated elsewhere, I only purchased this exhaust to keep my entire 8 all Mazdaspeed, except for my K&N intake.

HKS makes VERY good products. On two of my previous cars I had HKS exhausts. Great sound, great quality. But you do pay for that.

Looking back at my purchases I probably should have gone with HKS only because I want a little bit more sound from my 8. Then again, the intake is going in this weekend so it maybe loud enough then. :D

Who has the RX-8 Store exhaust? What's it sound like? I'm thinking about getting an exhaust but I'm leaning toward the dual muffler design.

so noone here on the board has a JIC yet?

I actually like the look of the JIC exaust with the titanium tips the most ( the full titan exaust being too rich for my blood :D)

anyone with soundclips or nice pics that would be great :)

I just ordered the Mazdaspeed catback. Supposedly it is the only one that keeps 100% of the warranty as long as it is installed by Mazda. It was damn expensive $900+ plus shipping. I ordered it from Corksport. I will let you guys know when it gets here.

has anyone tested any of the 'claims' yet themselves?

Thanks for the pointer mikeb. It's been added to the summary.

Anyone know what any of these sound like with a typhoon intake? (how the exhaust note might match with the different intake note and such?)

I know my K&N is way louder than my jic exhaust

any dynos on the exhausts yet? im leaning towards greddy full exhaust or hks

I have posted the graphs for mine. Search is your friend. Not much gains to be had with just a cat back. But at least we went forward, not backward as could be the case with a badly designed system. The RX-8 is well engineered. I think the design of my system is as non-restrictive as possible, bar not having an exhaust. And it meets noise laws as well.

How much gain do you want? I reckon if we picked the lowest of the before runs and the highest of the after runs you might be more impressesed. But we chose to publish a more average result that is more honest. Have a read on the racingbeat website as to what gains are to be had from a cat-back.

Next project is header pipes and a high-flow cat/midpipe.

Cheers,
Hymee.

Here is a sound clip of Autoexec exhaust. What do you guys think ?

Does anyone know the db of the stock exhaust and the B&B? Im leaning towards a B&B midpipe and cat back for my 8 but afraid it would be too loud for the neighbors >_< One thing I was wondering about was using a B&B pipe and the Borla catback, would that be any quieter? Im not even sure if I could do that, the idea just popped into my head.

Can anyone show me the weight comparions between the Stock, Greedy SP2, and B&B exhaust (only) please?
Does anyone know how they rank in loudness? with stock being the quietest I presume.
And also, ppl driving with new exhaust on the highways, do you find the constant, now louder, exhaust sound more unbearable than before?
Thanks!

And also a newb question..... the exhausts (not the straight race pipes) are still street legal right?

And also, ppl driving with new exhaust on the highways, do you find the constant, now louder, exhaust sound more unbearable than before?
Thanks!I have a Spintech system and it's not annoying at all on a highway drive (did So. Cal. to Portland, OR in late June -- 17 hours, no noise fatigue at all).

And also a newb question..... the exhausts (not the straight race pipes) are still street legal right?Laws vary from state to state. As a general rule, as long as it's not a lot louder than stock you'll be fine.

Racing Beat was not on your list, but I love mine. When cruising on the highway, it's not loud and it's barely noticeable. I don't why this one would not be street legal anywhere in the country.

Anyone kind enough to post some info on the Tanabe catback, though of getting it for my 8 in Sg. I've search thru the entire forum without much success, appreciate if anyone can provide some info on the sounds and gain achieve. :)

I'd have to say that from personal experience, if you're worried about the neighbors you should stay stock with exhaust and intake.
That said, if you drive carefully and keep revs low, I don't think any of the cat-backs offered are going to bother anybody (except for cops maybe).

I heard Bob's Spintech system at Sevenstock. I love it! It sounds tough. It is louder than stock, which isn't hard to do, but by no means is it loud. It isn't the prettiest thing on the planet but who cares. Just powdercoat it. I am very surprised with that system and would definitely recommend it.

I also heard Racing Geat's system. It is pretty quiet but probably nice at full throttle. It had a great tone and was not tinny or raspy sounding at all. Neither was the Spintech though. I approve of both.

I've heard the B&B and the Borla. Both of those cars had midpipes. They both sounded raspy and rice like. I did not like it at all. The tone was attributed to the midpipes as both owners have since removed them. I haven't heard any others that I have paid any attention to.

I need to get one of mine to Sevenstock next time :)

Cheers,
Hymee.

For sure! Bring it in person.

i am a college student so for me money is a problem. I was just wondering if there was a cheaper way for me to add more power for my RX-8.

i am a college student so for me money is a problem. I was just wondering if there was a cheaper way for me to add more power for my RX-8. Exhaust changes won't get you much of a power increase. The stock exhaust is very good. Aftermarket RX-8 exhausts are more for looks and sound.
That's if you want to keep your car smog-legal.

Does anyone know if any manufactuer has a exhaust system with four pipes at the back?
If not maybe i have to get one custom made?

Any decent muffler shop ought to be able to install multiple tips.

Why cantyou just remove thestock tips and snap on some new ones

The stock tips are welded on and there isn't any room to get a hacksaw in there to cut them off. It is much better to weld the new tips on than to use screws or something like that.
Yeah, you could do it yourself, but you still have to either pull off the rear "bumper" or remove the stock muffler to get to the tips. If you have the right tools, go for it. For the rest of us it's better to have a shop do it.

there isn't any room to get a hacksaw in there to cut them off.

floor jack + sawzall ??

So do I have to offer the quad tip option now? Hehehe. I talked L&L out of it.

i know these arent the best but its the ones i gotta work wid seeing dat i dnt have lots of money...but i want opinions which one u think is better?............GReddy sp2 eshaust? or Tanabe super medallion hyper exhaust? wut u guys think? they both cost the same but i ono which one is better... thanks guys. :confused:

Which system would you guys say overall is the best buy but with the least noise??

The stock system.

Does the B&B sound deeper without the mid-pipe? Or how about the B&B mid-pipe with the stock exhaust?

MazdaSpeed exhaust is basically a stock exhaust with the mazdaspeed logo on the tips that is all

Do you know this for fact?

Installed my RX8 store cat-back system about 5 months ago. Installation was pretty straight foward. The only hard part was lining up the rear exhaust & tips for even spaceing between rear tip openings. This system differs from most because it's a straight flow thru design. It use's two magna-flow cans and has a huge intermidiate pipe. Sound is great, louder than stock, deep & throaty, but not overbearing. The tips look great, bigger than stock but not as big as Greedy's which I have seen and do not care for (to big).
After warming up the 8 I ran it thru the gears a few time's to see if I had gained anything over stock other than better sounding, lighter exhaust. I really was not exspecting much after reading all the post etc. that you don't gain much hp. I think people are missing the point because this thing rev's so much quicker and pulls so much harder than stock. I was mildly surprised and pleased.
Just to make sure it was not just me I took the 8 down to my brother's to let him drive it. He's kind of a gear head with a fully retored 300ZX. I did not say to much about the exhaust other than it's ok I guess. He has driven the 8 many times before so I was surprised when he said how much harder it pulled and reved so much quicker. He was green with envy since he had put a cat back system on his 300 and felt like it was slower. He loved it and so do I. We are sure it added a few hp and it sure pulls now. Thanks for reading and rev on.

Anyone used the Tanabe system? I havent seen anyone mention that they are using it and notice they have one for the car.

You forgot the Mazdaspeed Exhaust

anyone got some home clips of their 8 and a greddy exhaust ?

What about SR's Catback- I've heard that their high-flow cat with stock exhaust sounds really nice without being loud, but I still have my 8 bone stock.

Hymee, those were some awfully pretty exhausts in your pics- especially the black ones- i like the sound clips too- I'm looking for nice sound without being obnoxious, and i'm afraid the Borla and Greddy would be too loud (but I haven't heard them in person). How do yours compare dB-wise?

Anybody with any of these exhausts live in lower Alabama (unfortunately I do)

Back to the SR catback, if you believe their website, the only difference between their GT-3 kit (claims 28+hp) and their GT-4 kit (claims 37+HP) is the addition of their catback exhaust. Admittedly, it is 15 lb lighter than stock, freeing up a hair of speed, but i find it suspicious that just adding their catback to the other kit gives an additional 9HP- or is this realistic?

Hey there, New user with a new 8. I just installed the Gready exhaust and a K&N typhoon intake. I could not be happier with the pair! I can't feel an increase in power and I havn't had any of the "issues" with the K&N yet. The Sound is increadible with the two paird, the greddy filles in the low and the intake puts in the Growl. I highly recomend the Greddy exhaust, It has two seperat cans, can't beat the price, and it was easy to install. A note on the install, I didn't have to take out the exhaust trim, just push and prod and it will go in no prob. :cool:

I ran across this on E-Bay, I think I'll buy it now.....

Hehehe - this thread is for aftermarket exhausts. I wish I knew they were worth money. We have taken plenty of them off, but I didn't think they would be worth much. But I guess I am only talking about the rear muffler, as we re-use the cat / midpipe / intermediate pipe.

Cheers,
Hymee.

hahah Ill give my Stocker away :)..

But on that Note.. I know have the Hymee Thunder fro Down under in stock in the USA ready to ship.. MY price includes UPs ground shipping on the Hymee.. I also have the best price on the Greddy..

Hi, well I've get my Greddy SP2 cat back system fitted and wow! it's put the sports back into sports car. I highly recommend the system the sound is fantastic! and the HUGE pipes realy look the part to.
Though it is a much travelled system as manufactured in Japan, then shipped to the States then finally shipped to the UK.
Thanks Bob for your info which helped me select the system.

Well i am waiting this week the sp2 and i really don't know what to do..I have seen and heard the new Trust Titanium catback and really loved it and its weight is only 5kg...What is the weight of the sp2???

thank you GREATLY for the exhaust summary, it really helped me see that there was more than just the GReddy exhaust system for the rx-8. i have a question because i didn't see anything about the MAZDASPEED exhaust. is that one bad? or just dont have any information on it? i was considering buying the MAZDASPEED exhaust, but a lot of people dont mention it at all xP just wondering :]

^^^ its not worth the money.. go with cheaper or custom.. in addition i think the mazda speed sounds the closest to stock and dont look that great either...butthat my opinion.

I had no info on the MS exhaust when I put this list together.
General opinion is that the stock system is about as good as it gets for a system with cats.
Just go with what sounds good to you.

what was decided about the midpipe vs catback... i understand using both will be very loud but would it be worth it to use one or the other.. if so, which one, mid pipe or catback? Does the midpipe throw the CEL?

i am hoping that the exhaust system mentioned here and midpipes are C.A.R.B legal or smog legal in NJ...since i don't live in california, which is a shame, the stricter exhaust demands don't apply to me.

I just installed my Magnaflow exhaust and have to say, it sounds incredible and looks so much better than factory. As for power, maybe, it feels a little smoother from about 5k up, but i dont want to say until the newness wears off. Ill have dyno #s posted soon.

What about teh MS Exhaust?

I must say... that Hymee exhaust is beautiful

If only I could get one in Canada (without getting screwed shipping up from US)

Hymee, do you have any 'approved vendors' or shops in Syracuse that sell your product?

For that matter, anybody know of good shops in the Syracuse area?

Hymee , I can get you one .. and if you have a freind across the boader we can ship it there and save you some customs..
But lets get real your not going to may an arm and aleg.. I had to pay customs to get them here..

Anyway there instock and ready to go.. Email me with you full shipping and ill gt you a quote.

but which inproves the rx8 the most?

Here is our custom exhaust for autox etc.
It will be used on the street.
7LBS from flange back.
He is going to get me some pics of the stock mufflers cut open. I guess they are very restrictive looking.
This system should help with the hp/tq.
Dyno tests upcoming.
Call him if you want one.
I told him to use the stock pipe for part of the exhaust but he didn't have to. Cheaper that way.

the lightest one

Hymee, do you have any 'approved vendors' or shops in Syracuse that sell your product?

For that matter, anybody know of good shops in the Syracuse area?

So, is Flop going to have the first Hymee exhaust in Canada?

Cheers,
Hymee.

good ?

might as well add Abflug and Odula to make it more complete

Hello guys,

I need your help.

I am thinking to install a new exhausts. I have been looking for the Racing Beat lately but some say that it is not lounder (or not much lounder) than the stock exhaust. I am looking for a lounder sound than the stock but not too lound. Any recommendations? What about the Borla or Greddy? Are they lounder than the Racing Beat? Are they too lound? I don't want to sound like a civic, if you know what I mean ;)

Thanks guy!

How do I post a subliminal message? :D

Cheers,
Hymee, Hymee, Hymee.

So Hymee, are you saying yours is a bit louder than Racing Beat :rolleyes:

Yes. I have driven a racing beat equipped RX-8, so I was able to make a first hand comparison.

Cheers,
Hymee.

Anyone know where to get Mazdaspeed exhaust tips? ;)

Seriously though, what's the best exhaust system that's as quiet as the stock exhaust. I prefer quiet as possible. :)

well first of all it can't because you may not know this but it doesn't have a 4 cylinder, it has a rotary engine which sounds very different than a honda 4. i suggest you read your users manual and read the stickys and FAQs so you know what the rx8 is before you start modifying it :)

I have had my HKS exhaust installed for a week now and love it! The install was very easy, the removal of the old was painful.............

It has become a little louder over the week but not obnoxious. I can't really hear it unless I am accelerating hard. The sound is a bit deeper than the factory exhaust and it purrs.....or grumbles steadily......very solid.....

I can barely hear it inside the car, but my husband says you can definately hear it on the outside. He says that it doesn't sound noisy, but definately sounds enhanced...........


:bowdown: HKS

HKS makes an extremely good product, worth the money IMO

hey bob do you know how much an OBX Cat-back exhaust adds? thats what i just installed on my 8, sounds nice... if you could let me know? thanks

Have any pics of the obx exhaust?

I see it on ebay all the time. How is the quality?Sound?

Any sound clips?

Does anyone know which exhaust system flows best. I know that sound is very important,
but Since I have the Greddy Turbo and concerned about the restrictions of the turbo which
will also quite the exhaust system. I currently have the Mazdaspeed Exhaust and I'am
wondering if maybe it more restrictive than other systems out there, I also have the RP high
flow cat, which I love..

Any info out there about this.....

speaking of good exhaust flow on aftermarket exhaust systems is the new racing beat single exhuast exit good in flow? because i see it maybe exiting on the rear right? if so -- is this the best exit i think maybe a left exit would be better flow wise but im no expert so any out there seen the new racing beat single exit exhuast? and would care to express their opions on it?

Good job! Nice research! Now, get that Darwin sticker off your ride and it'd be sweet!

someone should update this thread with new(er) clips. I.E the new ms exhaust. And clips with hi flo cat or midpipe. Seem like those thread about soundclips of midpipes and hi flo cats are popping up every week.

I am trying to decide between getting the MS exhaust and Tanabe Super Medalion Hyper Spec. There has been lots of good press about the MS system, but little info on the Tanabe. Does have any advice.

Thanks in advance.

Brett

i don't have either. But search for username modena, he has the tanabe exhaust fitted on with soundclips available. There is also clips of ms exhaust lurking around.

Power wise like mention many times both would not yeild any noticeable gains so decide on sound and style.

the tanabe setup will be louder, probably a little deeper and more aggressive and possibly slightly better power, the mazdaspeed gives 1-3 hp, they couldnt r&d mroe power with just a catback, but most companies get no more than around 5

Thanks for the tip. I checked out Modena's post and it does sound pretty sweet.

I think I will end up getting the Tanabe. It is a more expensive, but the tips are bigger (100mm vs 90mm), and the angled-tip complements the design to the car very well.

Thanks again...

Brett

Yep. Something nice about 100mm angle-cut tips :evil_laug :cool: :aroused: :naughty: :rolleyes: :rolleyes:

yeah it particularly matches the exhaust exit panels how they both are angled downward

i have the ms exhaust on and im considering the rb.please leave your feed back.ms sounds like stock to me.I know its a waste of money but would it be a complete waste, im going more for the sound than performance

Trying to be unbiased...

From my own experience, and if you are after some more noise... The RB system is louder than stock, but quieter than the "Hymee".

Cheers,
Hymee.

But are they both louder than the new MS version?

new ms version how is that different than the other one?

new ms version how is that different than the other one?

Originalk MS exhaust was single can and looked identical to OEM. New version is twin can design.

http://www.finishlineperformance.com/rx8/index.html

But are they both louder than the new MS version?


From what I have heard it seems that the Racing Beat is one of the quietest aftermarket exhausts, but one of the best looking, IMO.

The new MS exhaust lets you know that there is something under the hood, although I have never heard the Racing Beat I am going to say that the new MS is probably louder. This is based on hearing others opinions.

Here is a link to a picture of the originial MS exhaust:
http://www.mazdatrix.com/8exhaust.htm

anyone know the horsepower gain of just yanking the exhaust off from the cat?

not sure but i dont think mufflers take off nearly as much power as a catalytic converter. one thing for sure is your car will be loud as a MF

hmm, i've really been looking forward for a B&B exhaust or borla (i for one want a little shiver down my spine when going over 5k rpm ;) ). the thing is that i was told borla was bad quality. some days later, i was told B&B is even worse then borla. would someone be able to tell me (perhaps personal experience) how much truth is behind these words?

B&B and Borla are both reputable as high quality brands...havent heard bad things yet

tnx there :D
now i just gotta decide which of the 2 to go with :P

Had borla and had to send back.something loose inside and made churping noise at idle.Also not loud enough.then got mazdaspeed twin muffler and finish is better and exhaust note is sweet! much cheaper also like 200 hundy cheaper

really i thought MS was mucho $$$

Does anyone now which was is the lightest and that is not including titanium?

maybe greddy, thats a good question, i know for sure JIC's full titanium setup is but it doesn't qualify haha

I know for sure Racingbeat could be the heaviest.I know for sure its heavier even than the stock it replaces.

Hey guy's just joined the club even though i'v had my 8 for over a 1 1/2 and love it. I was wondering before i buy an exhaust if anyone knows info about the cat that is stock what is is made out of since i will be racing my 8 only was wondering what the inside is made of?
Thanks great info in here bob everyone has done their homework here.

Sup guys..i just brought my 8 on sat and when i walk in the parts dept. of Mazda, they had the racing beat exhaust on displays. Their price was like 634.00. If they are selling that at the dealer then i was wondering if it's street legal? Any idea? thanks

Mazda dealers in Australia fit the "Hymee" to brand new cars, both demo's and customers' cars :)

Cheers,
Hymee.

I browsed through the whole thread, and could not find the Trust PowerExtreme mentioned anywhere, so here goes. The Trust PE Ti can be found here Trust PowerExtreme Ti (http://www.trust-power.com/01exhaust_list/02_pe_ti.html), and is probably one of the best upgades. Costs a bit more than the SS ones, but:

a) produces some nice HP (around 7-8HP according to Trust/Greddy), and
b) is VERY lighter than the stock or ANY SS exhaust out there.

Compared to any other SS exhaust or the stock (all of them weigh around 17-18Kg), the Trust weighs in at 3,7Kg :Eyecrazy: We are talking about -15Kg weight saving just by swapping the exhaust....

As for noise levels, this exhaust is rather deep and throaty, but the noise increase is very, very modest. At high rpms you may not even notice you have an aftermarket exhaust (except for the backfiring :) )

its also very very expensive(around 700+ bux) and shipping from japan on a catback woudl be VERY expensive as well. Greddy makes a US version of one of their titanium exhausts which is simularly priced, except you can actually find them here in the states since its a USDM product and you don't pay over a hundred dollars to ship it over here

its also very very expensive(around 700+ bux) and shipping from japan on a catback woudl be VERY expensive as well. Greddy makes a US version of one of their titanium exhausts which is simularly priced, except you can actually find them here in the states since its a USDM product and you don't pay over a hundred dollars to ship it over here

Actually it's much more expensive than that. The retail is around 1250$, and we (in Greece) end up paying 1350E (~1500$) including shipping. I guess the price will be the same for the US. However you can't blame the company for the price, since titanium is a much more expensive material than steel ;)

My whole point was that a titanium exhaust more or less justificates it's price not only by the increase in performance, but also by the weight reduction. The SS exhaust might give you the same HP increase (~5-7HP), however only the Ti ones will also provide a 15Kg weight reduction. Can't beat that....

If you can find the same exhaust/design in titanium by a US company, then by all means go for it. However I couldn't find many other models, just the JIC one, which is much more expensive...

can anyone tell me about the RE-Amemiya one?

11 pages and we know little about the weight of the systems posted above.
Hymee - 15 to 16Kg
Racing Beat - heavier than stock
Stock - ??

Does anyone know the actually weights of the systems or was this exhaust summary really only for sound and price comparisons? Since we all now know that most cat-backs aren't going to add much in the way of HP, it WOULD have been nice to know the weights of the exhaust systems. Similar HP gains but the weights of the systems aren't...ie Racing beat being heavier than stock.

I'm getting the Mazdaspeed dual-muffler exhaust installed tomorrow. Are there any special break-in procedures that are recommended with a new exhaust? I don't think there is, but I wanted to make sure.

Thanks!

Yes ,
1/place foot firmly on acc. pedal till a beeping noise occurs then change gear .
2/Repeat step 1 until either
A / you fly into orbit
B/ you require laundry services

Ensure you bounce it off the limiter before you side step the clutch.

Drive by the nearest Police station and rev the piss out of it.

Then drive around their parking lot and repeat.

You forgot to tell him to then pull up to the front door and get out and wave to your new audience.

Sweet, I like these breakin procedures.

As long as you break something, then I guess any proceedure achieves the desired outcome.

Hey any feedback on that Mazdaspeed dual muffler sport exhaust?

I'm looking to do the same upgrade but don't want any truck sound.

Has anybody gotten that installed yet. Looks promising from the spec. data. Nice stainless steel cans!

I was originally looking to buy the Racing Beat Exhaust because I didn't want anything too loud.
I decided to get the new MS exhaust because the price was right, and someone posted a sound clip. It didn't sound like it was too loud.
After a week of driving with it, I can say I'm very happy with the sound.
If you real get on the throttle, it can be very loud, but at cruising speed on the freeway doing 80mph in 5th/6th gear, it's very quite. When I leave my house in the mornings, I keep the rpm's low, and it's pretty quite.
Once it warms up, it is definitely louder at full-throttle.
I planning on doing some in-car video at different cruising speeds do people can get an idea of what it sounds like.

- Cesar -

I'm picking mine up later today. Will let you know what I think soon!

Any idea where the sound clip for the ms double can is located?

New RX-8 Exhausts Availability Update
http://www.rx8club.com/showthread.php?t=81039&page=4&pp=40

Does any one have something similar to the following:
A single (biggish, about 16 plus inches long) canister at the back with single exit and cat removed with a resonator, where the standard one used to be, (also not too small).
As I designed, must still double check all my measurements etc, a exhaust from front to back with single exit and other type of tailpipe from idea of some website, I want to know on sound / loudness of such system before I finish mine (mine will be custom built) thats the only way here in SA anyway.

If anyone want some detail, pm me with email adres and i will send the basic idea in one page pdf.

I really want to get a exhaust for my rx8. I cant decide which one is the best for what i want tho. Im looking for a deeper exhaust note without any kind of "ricey" sound. Dont want it too loud but definitely louder than the rather quiet sound it has now. I'm leaning toward the mazdaspeed system but i'd appreciate any advice or input. Thanks

Search for sound clips...I went Borla and love it, but know others with MS, RB, Corksport and others that love those, too

My mate and I drove down to R-Magic last weekend. Its about a 50 km hike from where we live in Tokyo. Took 3 hours... Gotta love city traffic. He was looking for a quiet exhaust at idle and motor way speeds and something more lively under heavy right foot application. One of the R-Magic guys took us out of a spin in the demo car on a little test course. At first just cruising a long it really didn't sound anything above stock. My mate was thinking that it was maybe a little boring for him - as in, whats the point if it sounds just like stock.

Then we hit the test course going through the rev ranges. Wheel spin in second gear. The odd backfire on lift and a wail of glorious sound following us around. I have the Racing Beat one myself which is quiet in comparison to this. Its intoxicating. Sounded like F1 in Monaco tunnel. He signed up for it with out batting an eyelid :-)

Off to the combini to pick up some cash and the damn thing was fitted when we got back. Took them all of 40 minutes or less. Great service. Later in the day we went for a blast through a road in the mountains about 60 kms away. There we found a series of 20 small tunnels where we were a little immature in terms of noise pollution. Is this beast really that quiet at idle is all I can think about. I love that exhaust and the sound it makes. Secretly wanting it.

I haven't been for a spin in my car since as been at work all week. Heading to Super Autobacs tomorrow to the Mazda Fiesta day. AutoExe, Revolution and Trust will be there with demo cars. I plan on picking up some toys...

Tom.

Mental note to self...

beers :beer:

That site was very helpful but i did notice that there seem to be 2 versions (or more) of the mazdaspeed dual muffler system. One that I saw had round oval shaped mufflers and were not polished (the tips were of course) and the other i saw was completely polished and had bigger flatter mufflers. Any difference in performance or sound with these? I've heard the soundclip of the mazdaspeed mufflers but i'm not sure which is which now. Anyone know?

That site was very helpful but i did notice that there seem to be 2 versions (or more) of the mazdaspeed dual muffler system. One that I saw had round oval shaped mufflers and were not polished (the tips were of course) and the other i saw was completely polished and had bigger flatter mufflers. Any difference in performance or sound with these? I've heard the soundclip of the mazdaspeed mufflers but i'm not sure which is which now. Anyone know?


difference in power is nothing if any... the one that has two mufflers is the new one... much louder....

the one with the big can that looks like the stock muffler is the old or first one...

beers :beer:

so the mazdaspeed muffler system that has the dual mufflers that look like "cans" is different than the other one? Check out that website again that you gave me and lemme know if that one is decent or if i should shell out some extra bux for the other one. "The other one" i've seen is on a couple websites but i found it on mazdatrix.com. Thanks for all your help!

check pm

Well guys, i finally ordered my mazdaspeed dual muffler system this past weekend. I can't wait!!! Finally I'll be able to hear my RX!! Ill try to get some video or sound clips on here.

Wow!! U guys were right about the ms muffler system!! Sounds freakin great! and holy crap what a sound at 8500 rpm. Thanks for the advice again everybody!

Hi guys
us lot over the water seem to be well behind you lot....
whats your thoughts on the Borla, as we have all been trying to get hold of them.
and out of the various systems that our members have over here the borla sounds the best other than made up ones!!!!!

also anybody know of some good and relevant exporters to supply us brits with Borla system. cheapest upto now is £580 which still seems steep.
your thoughts please.
cheers

what did you pay and from where?

Wow!! U guys were right about the ms muffler system!! Sounds freakin great! and holy crap what a sound at 8500 rpm. Thanks for the advice again everybody!

Does any one have the "Header-back" systems from Greddy, I'm lookin at gettin it and wanted to kno if anyone was having problems

Has anyone had any issues with the B&B cat-back exhaust leaking at the connection between the pipe & muffler? I bought mine 2nd hand, and had to order a new gasket for this location because the other one was shot, and upon installation, they just don't align properly at the right angles, so there is a constant leak out the bottom of the connection. Anyone else have any experience with this??

Received my Hymee exhaust today and had it installed.

IMHO, this is the best sounding exhaust. The tone is very low (no rice here), and just the right amount of volume - I would say medium volume with a deep, great sound when your on the gas and just a low volume rumble when you are cruising/idling. If I decide I want more volume later, I may add a hi-flow cat - we'll see.

On the looks side - those 4" tips sticking out the back look great and really fill the exhaust frames well without requiring any trimming to install. I got the stainless version and while you can't see those gorgeous mufflers from the back, they still look great when you look up her skirt.

I did have a custom shop install mine. I thought about doing it, but after watching it get installed I was glad I had a shop do it as getting the intermediate pipe off the stock muffler was tough and they had to expand it a little to get the new connector pipe inserted all the way. They also had the right tools and experience to get everything lined up perfectly straight before tightening down. Well worth the $80 to get it perfect.

I highly recommend this system. Time for a Ride!!!!

Probably answered before, but what is the size of the tips on the of the MS sport exhaust?

anyone willing to trade their RB exhaust for my borla? lemme know peeps

so basically there are no sounds clips or recomendations regarding the JIC ti exhaust? as we all know, ti is very attractive but what im really after is the weight loss. not to mention the un-matchable sound...

also, is there any news on the re-amemiya? what is it, possibly where to get it and at what price?

scratch the RE-Amemiya question...

I want to thank Bob and everyone who has posted here. It has made the job of finding info on exhausts much easier. I just placed my order for Hymee's exhaust from MazdaParts.

So no response on this?

check out the tanabe ultra medalion exhaust for rx8 looks good sounds like a good bet for performance to

Finally ordered my MS sport exhaust. Can't wait to get it.

Finally ordered my MS sport exhaust. Can't wait to get it.

You will LOVE it!! Got mine installed last week (along with the MS CAI). OHHHHHHHHH BAAABBBBBY!!! :)

Just got it yesterday. Not bad, ordered it from Rosenthal on 12/22 and recieved it in 5 days through the Christmas holidays. It looks sweet. Can't wait to install it.

My Hymee exhaust arrived last night. After reading the instructions, I did just like Jax RX8 and took it to the shop this morning.

I second everything Jax said. This is the way it should have sounded when it came from the dealer. Hymee did a great job!! :rock:

which one in the same Price range , greddy or BORLA???? want a real quick answer if possible i dont want to clog up this thread, or its just a personal opinion post real quick. thx

I'd say if you plan on changing out your cat pipe for a hi-flow cat or a catless midpipe, go with the GReddy. The Borla sounds pretty ricey with a hi-flow or straight pipe.

If you're keeping the stock CAT, it's a toss up. I have the GReddy and love it, but the Borla sounds good too.

Man..I really like that Super Dolphin exhaust on the RX8. Its a lot of money, but looks very different than anything else out there. Looks like a motorcycle exhaust/extractor with segmented welds similar to a ProCircuit dirt bike pipe. I guess the $1600.00 price tag will make this exhaust a rarity, but I would love to hear how it sounds regardless.

Hey everyone is talking about B&B and Borla, but the Greddy header back system sounded better and claimed the highest HP gain. Why does no one like the greddy? I mean yes its not street legal but there are so many ways around it and in my other car. A Mustang cobra. I dont have much street legal performance parts on there and have never been questioned about them when I have been pulled over. SO what is the deal?

The big deal is that some people still want their cars to pass state inspections.

I know but even living in a state where smog inspection are required, there are ways to get around it. Me for example I have my car registered in another state. Even if I did not, as long as you keep the parts for your old exhaust then you just put it on, have it inspected then take it back off and it does not cost much. Maybe me being military makes it easy for me to have my car registered in another state. I am thinking about getting an exhaust for my 8 and I want to know what street legal one is the best overall. I dont care if its a little loud. I am not a picky person when it comes to sound. I care more about overall performance. Thanks for your response though.

Has anyone used a cat delete and a cat-back exhaust from the same company? it sounds like everyone likes to switch them up a bit, but i was wondering if anyone had the cat replacement 3" pipe and the cat-back exhaust from racing beat?

Probably answered before, but what is the size of the tips on the of the MS sport exhaust?

I went throught the hole thread and I didn't find the size of the exhaust tips....I'm looking to buy the Mazdaspeed dual muffler exhaust and I would like to know the size of the exhaust tips and if possible what is the size of exhaut (is it 3"...)

IMO the JIC Ti is THE best RX-8 exhaust for the money, and I think you mean it's un-matched lack of sound, it's not much louder than OE with a nice tune WOT ... and extremely light for a full length dual tip system

unless you're racing, exhaust noise is for attention wh0res and wannabe poseurs :hahano:

It is 3.5 inches, sorry for the dirty tips. It sounds GREAT too. I'll crawl under the car later and give you the pipe demensions.

does anybody have a hf cat and the JIC? how does this combo compare to the hf cat and RB exhaust?

Today i have dyno'ed my RX-8 header system on my RotoTest hub dyno. Mods: Shell V-power 99 octane fuel Feritta race cat with 2.5" front silencer and single rear silencer with double 2.5" outletsand 3.5" "Gold tips" With the stock exhaust manifold 196 rwhp@8500 rpm, with the new header system 202 hp@8000 rpm. That's a gain of + 7 hp at cranc! The header is a prototype and therefore is made of steel and Mig welded. Now my Tig guru Peter is making it out of stainless steel. Hope to see +10 hp when the header is done. And this is without remapping the Ecu it 's just bolt on and go! Car is really fast, and have clocked 0-60 mph with stock manifold in 5.86s. Now a little bit quicker! I am planning to sell these 3 exhaust parts to Usa if everything goes the way that i want.

Thank you for the info I appreciate it. :cool:

Can someone with a JIC or RB exhaust please post a sound clip? I curious about the sounds of these at at constant acceleration as well as revving. Most post the sound of revving from idle, but what about simulated cruising speeds?

Thanks in advance.

someone said that the RB exhuast made the most hp out of all of them and they had dyno charts to prove it.

someone said that the RB exhuast made the most hp out of all of them and they had dyno charts to prove it.

that would be a no... in the real world they all put up less than 10 hp. much less for most. this it with a stock cat..

a bit more with a mid pipe or hi flow cat...

the turbo xs was dynoed at i think + 22 hp with its midpipe. it is a three inch all the way back...

but it is way way loud...

beers :beer:

Does anyone have an input on the Agency Power titanium-tip dual outlet exhaust? It looks to be of high qualitly- but I'm torn between that or the B&B system. Or the JIC titanium system, but it's a little on the pricey side.

Dave

You can't have your vehicle registered in another state if you live in AZ. Arizona sucks. You can have out of state plates or registration or you get a freaking ticket. Even if you just moved here- I got one. Even if you're a student! AZ is ridicoulis. I have too many horror stories of the terrible laws here.
But anyways, if you have your vehicle registered out of state, how do you get your state plates and tags for it? You can't, or can you? I don't see how you could goto the DMV and get California plates with a Nebraska registration. Too much hassel.

Dave

B&B: Price is about $950 for the cat-back system plus the race pipe.
Vivid Racing claims a 19 HP increase over stock


:rofl:

sound clip of hymee with rp supercat anyone????

I am looking for sound and or video clips of the RP Super Cat with the Hymee, Rx8Store, GReddy SP2, Mazdspeed, and stock exhaust. And what others think the best combo is minus stock exhaust.

For me to get an aftermarket exhaust, I would have to drive a good 2 hours at least to buy it and have them in stall it. If I want to keep my stock system in case I need it, could I fit it in my car to take home?

you could do it yourself... really.

and sure you could put the stock exhaust in your car and driver home with it.. but the windows will be down...j

Just installed the RX8store catback today. I wasn't very pleased with the packaging as there were a couple of holes in the box and tips were slightly scratched intransit. I would've installed it myself, but it was missing the hardware(bolts & gasket) and too be honest, I was just being lazy. Turned out to be a good decision as my muffler shop wasn't able to utilize the stock exhaust springs. He ended up modifying a set that he had to work with the new center pipe exhaust flange.

The stock exhaust will fit in the back seat as long you have them remove/cut the center pipe. I'm not sure if I'd want to drive two hours with it back there though as it shifted around alot in my short drive home.

I too am looking at getting either the RX8STORE catback or the GREDDY. You are pleased with the tone of the exhaust? Any sound clip?

If putting an exhaust system in yout back seat, make sure not to nick or scratch the center console, I put my full turboxs system in my car and put a tiny nick in the silver trim piece....

I too am looking at getting either the RX8STORE catback or the GREDDY. You are pleased with the tone of the exhaust? Any sound clip?

I've only had it on for about a day now, but it has a nice solid deep/low tone without being raspy. I'm sure it will mellow out as time goes on, but right now the only time I don't hear it is when it's parked.

No sound clips yet, maybe this weekend.

I just installed the RP Supercat, and i want to get the Racing Beat catback, how much louder is it goin to be

I just ordered the Supercat 3 days ago, how does it sound with the stock exhaust?

MS Sport Exhaust was finally installed yesterday. All I can say is it's an amzing improvement. I like it!

jzrx8, the supercat with the stock is really nice, it's alot louder when on the gas but when just driving around its hardly noticable, also u can really feel it pull in higher rpms from 7k on. install should be easy it only took me and a friend 45mins

I would definitely have an old blanket across my seats if I put my old exhaust badk there.

I am not worried about the install at all, I will just put it up on my lift at work and use my air tools so it should take even less time.

yea thats what i did, it just took awhile to get the cat cooled off

In a matter of a few days. my MS exhaust tips are turning goldish. I remember reading, but can't remember...What are people using to remove this discoloration from exhaust tips? I tried my Never Dull, but that doesn't seem to work.

Thanks

For some sick reason I am intrigued by the RE AMEMIYA Super Dolphin also. I doubt it is one I would buy. I just like the way it looks under the car. I think it would be very heavy and worry that it would sound rice.

I was trying to shrink the picks down to post them but I could not get the size right.

Good job in getting all the info together mate.

Here is a few more addition/choices for exhaust:
Re-Amemiya Titanium:

Stainless Steel:

I have Greddy/Trust Titanium Exhuast on mine, it looks and sounds great too.

Did u mean the tird section exhaust system are all legal on the street I'm in CA....

OMG, this is not an exhaust, but I found the first must have part for my RX. This RE Amemiya Rear Diffuser Piece:

Well maybe me being military would help the fact. I have my car registered in Oregon or Washington. I use my current mailing address here for the plae for them to send the plates and decals. I always have a friend in another state where I know that there are less strict laws. Like window tinting for example. When ever I go on vacation, if there is something like registering or something like that to where I need to get the vehicle smogged. I just get it done while on vacation. Its time consuming but its worth it in the end.
