carismaautotec.com has tanabe exhaust on their 8 but it's not avaiable yet.

 

just some fyi on the prices canzoomer has a great price on the greddy exhuast! http://www.canzoomer.com/Price%20List/PRICELIST.pdf

 

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

 

mikeb does

 

Heres my contribution to this thread :D

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?

 

No offense, but you WAY over-paid. You can get them for $700 shipped or less...

 

any sound clips of the HKS ?? cant find them anywhere ?

 

hks

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?

 

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).

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.
