Yesterday we got a new custom Catback fitted to Wildcard's (aka D.G.W.) '8. Nice looking car in the silver!

Wildcard drove up from Newcastle to get the job done. (9hr drive)

I've attached pics in the following posts (my hosting is up to it's limit at the moment).

The system comprises:


Stainless steel rear pipe. Couples to standard mid pipe with custom made connector. Flange bolted to muffler assembly.
Custom made mandrel bent stainless steel splitter.
Twin custom made stainless steel mufflers, double offset. Mandrel bent inner perforated tube. Highly polished.
Stainless Steel Tail Pipes.
Double wall polished stainless steel tips. They are "MagnoFlow" style. The tips alone cost a friggin fortune (~$160 each)!
Standard hanging points.
Can unbolt and be replaced with standard system. Standard system not butchered for any "bits".
Sounds freaking awesome.


Wildcard, myself and Les spent lots of time sourcing the best looking tips. Wildcard Sr. also liked the "quads", but the pipes look a bit small. The ones we ended up with look genuinely tough, and make my stockers look woosy in comparison!

The workmanship is top notch. Les is a highly regarded "pipe specialist" - a real craftsman. Seeing him in action really is a treat.

"The sound?", I hear you ask! We fired it up and it burst into life. It was reasonably quiet at idle, but louder and deeper than stock. Just a nice subtle note to let you know something is there. Blipping the throttle brought a huge smile to Wildcard's dial. The odd crackle on the over-run, but not over the top. We let it warm up a bit, then gave it a few short higher RPM bursts. Very nice indeed.

What was really impressive was when Wildcard first took it for a drive. I was waiting out the front of the shop, and he came out of the side street, and gave it some going past me up the front street. It sounded absolutley awesome! That is not something I would say lightly, having come from the V8 world, where the word rice conjures images of disgust! I followed Wildcard for a a few km and was continued to be impressed.

I spoke to Les later that night, and he said all the boys thought it sounded awesome on the drive-by. That is a big statement from a bunch of blokes in back T-shirts and jeans more used to custom building pipes for big-block drag cars and custom hotrods.

It was getting late, but we managed to get to the independant dyno shop (PowerTorque Engines) to compare dyno runs. I don;t wan't to publishing anything yet, as it has become apparent that perhaps the "safe mode" does come into play on the dyno - the new system really started to take off in the mid-high RPM range, but then it was obvious (to the trained eye of our Mark Mc) that something funny was going on, as the computer appeard to be holding it back. Stay tuned for more on this. One thing I would like to do is rig up a signal generator to plug into the wiring harness, and simulate the front wheels turning. In my spare time :eek:

Anyway - enjoy the photo's. If anyone is interested I can arrange.

Thanks to Les for his time and effort in getting this going!

The underside of the muffler/tailpipe assembly:

Muffler assembly in progress:

The complete system (less a couple of nuts/bolts and springs). Did you know your rotary engined RX-8 has 2 valve springs :)

Side view of one of the tips:

View while on the road - it was getting dark :(

So what did the whole system cost?

The system is going to be $800 - $850 fitted (but I am waiting for confirmation). Wildcard got a special deal ;) He also took digtital video/audio but is unable to download ATM due to lack of suitable equipment (firewire etc).

Sorry I can't advise on the actual price, but this a complex situation. PM me and I can give a private summary. If enough are interested I will probably arrange something similar to the grills.

BTW - This might look like some thinly veiled advertising... Don't worry, there should soon be a Hymee sponsorship banner here real soon!

My objective, as with the grills, was and still is to provide car enthusiasts like me high quality products at affordable prices. And I won't be giving up my day job!

Cheers,
Hymee.

I forgot to mention... Mark from PowerTorque thought it sounded spot on as well. That is a big statement from a V8 supercar engine builder, ex professional racer, top-10 bathurst finisher, and someone who like to poke rice jokes at me.

He also said the work Les did was top shelf stuff.

Cheers,
Hymee.

It looks high class and can't wait for the performance figures to enable some comparisons!

Yes - I am awaiting the chance to be able to do better dyno checks without that "safe-mode". Something I am looking into now.

Anyone got a G-Tech Pro we could do some street testing with? Maybe that goes on my Christmas wish list :)

It appears from what I have read elsewhere there is not a real lot available from the cat back. Indeed, it would not be possible to make an exhaust any less restrictive than this one other than going straight out through the rear rotor crest!

I believe that most of the restriction in the stock exhaust is probably in midpipe/cat/exhaust manifold in the first place. The next project is a new mid-pipe with a hi-flow cat. Then headers are on the agenda. The benefits of the new cat back should be more applicable to a free-er "front half" of the exhaust. And then a tune as well sometime :)

Cheers,
Hymee

So tell me , does it throw flames out the back

Wildcard did see something when it was on the Dyno, but it was not really that dark yet. We didn't really try. Wildcard might be able to add - he had the pleasure of ownership since, and has been doing a few k's to help the computer re-learn (if required).

I was lucky enough to drive it round the block for him to hear what she sounded like from the outside. All I can say - It was fun! - yes, dear readers - even more fun than normal!

Cheers,
Hymee.

Hi all,

As you can imagine I'm very happy with the new exhaust. Sounds great when you step on the gas, but it's also quiet when you want it to be. Exhaust note at idle is a little deeper, but not much louder, so you don't look like a dick sitting at the traffic lights. Cruising on the hwy is the same - a little deeper but not really much louder than stock. When you want to make some noise though, oh baby! It'll be a while before I turn the stereo back on again I think. I can also get a nice crackle out of the exhaust when I come off the accelerator quickly.

On the subject of power, I went back to the Dyno this morning. Same problems as yesterday with the ABS light coming on at about 7000rpm. Performance is better than stock up to that point, but then the power drops off. The dyno log shows a change in the mixture once this ABS light comes on, indicating that the ECU is doing something to the timing or mixture as the ECU engages some sort of 'safe' mode. So the real answer wont lie on the dyno until someone can trick the computer.

On the road though, there is obviously no ABS light at 7K rpm and the car continues to accelerate nicely. My butt tells me that there is probably a little bit more go, but as has been said elsewhere, there aren't really any huge gains to be had from a catback system anyway. My gut feeling is that there is an extra 5-8 kW at the wheels.

Aurally it's a different feeling though. The deeper and louder exhaust note is a pleasure to the senses, so even if I'm not going much faster, at least I feel like I am!

Thanks to Hymee for all his great work again in getting this project off the ground.

Sound files will have to wait until I get back to Newcastle in the new year. By then I should have my Rotary Extreme intake installed as well.

Wildcard

Oh yes, I'll be going out later tonight to see if we can spit some flames! Video camera at the ready...

Nice!

Excellent pics. Why did you choose two mufflers (like the HKS RX8 catback) instead of one (like standard / Borla model)?

It's just that I've been talking to a company here in Adelaide that is currently prototyping an exhaust on the RX8, and they believe (but have not confirmed / tried yet) that one muffler might be the go ... something about gases mixing too early or something. I wasn't quite paying attention to the reason at the time.

DDB,

Mmm - the gasses have already well and truly mixed waaaay before the mufflers.

Ask around, ask questions. The hard part is often sorting through the good advice from the bad. Ultimatley you have to decide that for yourself.

The scientific reason we used 2 mufflers was to achieve efficiency in the flow. We believe we have done that with our design.

I could write up a really smick looking marketing perspective/sales pitch, and talk about all the research and development that went into this. And how we got acoustics specialist involved to fine-tune this bit and that bit. Some people might believe that. But I don't want to go down that path. It would be bending the truth.

I do want to share with people what we have achieved. People might choose to take copies of the pictures I have posted to other shops and hope they can do a good job. Some places will be able to, but we have seen many shockingly built systems from places that should now better. I also had great confidence in the people I entrusted my first LS1 exhaust to - I was poorly disspointed. But I now have a good relationship with Les after he did a proper exhaust for it.

I am hoping to save people from that anguish, and present a ready made, high quality system that can be shipped anywhere, and simply bolted up as a replacement.

We didn't employ any acoustic specialists - but those who have heard it are mighty impressed!

However, we did employ the many years of hard won experience of someone I can trust.

Cheers,
Hymee.

Hymee... that looks great!! Definitely one of the cleanest and nicest looking bit of exhaust workmanship I've seen for the 8's yet!

Hymee,

That's cool. I'm sure the guy has his own ideas and agenda (the guy I was talking to). Like I said, he was talking about 1 muffler, not two - but since his friend's RX8 is the prototype (to be done this week or next) - no firm decisions have been made.

From looking at the pics of the HKS exhaust, they went down the same path as you. And I think HKS would have done some extensive testing on their own.

The shop also (obviously) wanted me to use one of their custom from scratch jobs rather than use a bolt-on.

But I am interested in what you (and Ric Shaw) and anybody else have to offer before I decide. FWIW, what sort of price would you be considering to ship the unit to Adelaide? Hit me privately if you don't want to let me know in public.

dbb,

I shipped my old "before Les" Commodore exhaust to a guy in Melbourne. He arranged the freight company, but it cost him $80 from memory. That was for a full V8 twin 2.25" system from headers to chrome tips, from Les's shop to his place.

I'll contact "The Dovel King" on the LS1 forum and find out for you and let you know. Whatever cost the actual freight is we need to ad a couple of bucks to bubble wrap it etc. (In my huge shipping room hehehe. I think that is my living room spelt wrongly)

Cheers,
Hymee.

Looks like another quality 8 accessory from Hymee! Great work.
When I finaly get around ot ordering my 8 I know who I will be talking to regarding accessories... 1 Hymee grille & 1 Hymee cat back. :)

Hymee catback... nice.

Give me a quote later on. Sound like the Amuse titanium one is about $3k so your one is cheaper (and stainless steel too) :D

If it is under $1K installed then... though choice. Spent another K I can get the RE Amemiya in HK. I guess I should support local business

Hymee, to all intents and purposes it looks like you've done it again! our own homegrown guru.

Looks awfully like a tractor exhaust: do you think mine could be invoiced as such?

JAX8

THE TAX COMMISIONER WILL BE ASKING SOME QUESTIONS ,
HYMEE make mine out to 2002 honda jazz exhaust replacement as my rx8 is not tax deductible , ha ha ha

An invoice - I would have to charge more! How about "Custom Pipes?" - sounds a bit agricultural.

Takahashi - sounds like a tough choice - <1k or 2k? If you think it will be a better system if I charge more I can accomodate you on that ;)

Stainless should be good for 20 - 25 years.

If anyone wants a cheaper version if they are only going to keep there cars for 3 years etc on lease, then we can do the same in aluminumised mild steel for roughly (very) half the price, same quality. Should be good for 5-6 years. Remember - you can always bolt-on your old system at disposal time.

Cheers,
Hymee.

Hymee

Is there a weight difference between stock exaust system and the hymee exaust ?
Do you no what this may be ?

Will the cheaper aluminised- mild steel system give same power output as the stainless steel one?

michael

Good question L&L.

We didn't weight the whole lot, but the stock unit was heavy.

The rear pipe would be much the same. I'd reckon the muffler assy would be lighter.

There should be no difference in performace between the SS and MS. They will be manufactured using the same methods. The design of the mufflers will be the same non-restrictive design. Just a difference in materials.

I personally believe all the cat backs would be within a bee's dick of each other in performance if they are built right. The bulk of the performance in the exhaust will come from a better mid pipe, and headers. The Hymee Exhaust Stage II (Mid pipe) will have a hi-flow cat, so as to retain legality for street use.

Cheers,
Hymee.

Hymee

I have read that the TITANIUM exhaust system had an incredible weight saving of approximately 20lbs over the stock exhaust.
The down side is the 3-to 1 expense conponent over stainless steel .

By the way i never knew bees had dicks ? your eyesight is definetely a lot better than mine , did you make this observation while they had a hard on ?ha ha ha. or were they flying past you flashing .?


Will the Aluminised / mild steel exhaust be able to handle the extra heat from the hymee stage 11 system with the mid pipe and the high flow cat? What is their life span ?
Michael

[aside]

on the way home from work tonight, I passed through the Adelaide CBD and stopped off at a specialist high performance exhaust shop [name supressed].

I should have worked out something was wrong as the place was full of commodores and WRX's. The shop I went to earlier today (which I have been recommended to by multiple sources) had a 350z, and 67ish Pontiac GTO and a Boxter S being worked on.

Anyway, the place with the commodores had a smarmy sales guy/manager who was obviously thinking he could pull a fast one on me. A stylised conversation follows :

"I''ve got an RX8 (pointing out window) and would like to know if you've done any work on one yet?"
"Sure, we've done two"
"Well, I'm interested in getting a cat-back exhaust fitted and I'm just exploring my options"
"[sales pitch]"

Anyway, the guy goes on to say some stuff about how turbo models like mine need this and that. Hmmm ... the Rx8 is a turbo? Surely he would know it was normally aspirated if he had worked on two cars?

"Dyno tests show ..."

I pointed out that the ECU stuffs the dyno tests.

He said he had an override program to stop the ECU reading wrong.

That's when I walked out the door ...

HKS, Trust, Racing Beat, Mazdaspeed, Hymee................sort of rolls off the tongue!

At least I'm game to put my own name on it :)

Excellent work walking out dbb. It is a sad fact that there are people out there who are only out there to make a buck and are prepared to lie through their teeth to do it. I think finding some one you can trust is the hardest part for those of us who are new to this whole scene. That's what makes the forum so great.

Getting back on topic, I went out tonight and tried to spit flames out the back of the exhaust, but I didn't have any luck. I gave it a good shot too.... drove it really hard and kept the revs high for about 15 minutes prior. But no flames (some would say that's a good thing). It sounded pretty good trying though!

Forgive me lord, for I have sinned. :eek:

Wildcard - we forgot to put the extra fuel dumps into the mid pipe :)

Actually thinking about it a bit more...

Didn't the US guys reckon you could do that with the stock exhaust? Has anyone done it here?
The US cars have a different tune - lots richer, remember! Why do they make it richer - to dump more unburnt fuel over the cats. What is that unburnt fuel is eventually ignited downstream?


I always remeber how wowed I was when I first saw race cars spitting flames on the overrun. First it was RE RX-3's and 4s at Lakeside - I took a good photo once (mental note to self - scan that old print in and post it!), then the Turbo Sierra's. Then to my absolute delight the V8 supercars (or maybe it was the last of the Group A's???) started to do it as well.

Some other food for thought. It sounds OK to me at this time of night :)

Cheers,
Hymee.

Hymee, well done! Wildcard - good on you for being the guinea pig!

Is a midpipe (no cat) in the works at any stage? That would sure be applealing.

Also, how loud is loud ?

Hey KAS!,

The Hymee Mid Pipe will have a hi-flow cat and be street legal. And it won't need any O2 trickery. I don't believe in fooling the computer. (well - maybe into thinking the wheels are spining on a dyno...) Cats are not a problem if they flow enough.

The definition of loud. Well - how soft is soft? How fast is fast? A bit subjective, but all who have heard it think it is awesome.

I reckon we nailed it. Perhaps I am biased, but you don't lie in bed thinking about these things for no reason ;)

Cheers,
Hymee.

Sounds good! (the mid-pipe idea) hi-flow cats do cost alot of money however.

I ask about noise level as i drive for a large part of my work with clients and too loud can spell hooligan rather than sports car finatic.

Kas,

We were cautious about it being to loud. But we were very happy with the result and that is was not loud. When we put the dB meter on it I'll let you know. Have another read about Wildcard's opinions on the noise level.

Cheers,
Hymee.

Any chance of an mp3 so we can compare to the standard and borla mp3s which are available somewhere on this site?

Still on the topic of exhausts -> Rotary Heaven here in SA were talking to a counterpart in Vic who fitted a custom cat back exhaust. After two different attempts they are taking a breather, because each attempt resulted in a noticeable reduction in power.

No reduction of power for us thankfully. The dyno does show a reduction in power above 7K rpm, but that is due to the ECU entering some sort of safe mode. On the street though, this doesn't happen and there is at least as much power as stock, probably marginally more. If they (the guys above) are crying foul about power after throwing it on a dyno, they are not really getting the full truth I don't believe.

How loud is loud? Well like Hymee said, I think we came close to nailing it. It's quiet at idle and while cruising, but you can also really make it sing if you want. I wouldn't go any louder if you know what I mean, but I don't think it's too loud either.

As for sound files, I should be able to sort something out next week when I get hold of my mates laptop. Sorry guys. I hate being away from my home PC too, but I'm on holidays at the moment.

On the subject of going cat-less. I remember reading a link that Lock&Load posted a while ago where one of the US shops found that the only way to get decent gains was to remove the cat all together. The result however was that the exhaust becomes extremely loud, probably more than most would find acceptable for daily driving.

On Holidays - I would be in 7th Heaven if I just had that exhaust fitted!

Or is that '8th Heaven?

Cheers,
Hymee.

Can't wait till Wildcard gets his vids posted. I just listened to the HKS video in the main perfromance forum, and I don't think it is as nice - but hey I'm biased :)

In reality, they might be similar - it is hard to compare recordings to the real thing sometimes.

Can't wait - Wildcard!

You should do a write up in the Tech/Performance forum on it.

Cheers,
Hymee.

I'll wait till I get my intake and post the combined result in the "customer report on the rotary extreme intake" thread.

can't wait Wildcard....excellent looking work Hymee

I had an extended drive of the Wildcard's beast last night. The main thing I needed to check was for droning. There was none whatsoever, at a variet of cruise speeds and RPM's. That was good news.

One other benefit reported bt Wildcard - the temperature in the boot is noticible lower now he has his Hymee Cat-back.

Cheers,
Hymee.

Hi Hymee, new member waiting for mew car. Can you tell me what it would cost to get a mild steel cat back exhaust to Canberra all up?

Ta
breedy.

Is this the Dale Brede that drove in the Konica series?

Yes pepe it is

Haha, last time I saw you, you were trying to sell me a 350Z ;) my how things have changed :D

In the new year I hope to finalise the costs for the exhaust system (Cat-back for now, cat-forward later).

My contacts are on leave at the moment, so it has been hard to firm up any arrangements over Christmas/New Year.

At least Wildcard got one!

Cheers,
Hymee.

Well, dale, we have a mutual friend. Crampy at Manta. He also built my race car.

Welcome to the RX8 club!

Thanks AMG its nice to be here. I am talking to Cramp about doing some things to the new car.

Pepe,

I would have bought a zed myself, but with two kids it is abit more practical. I do like both cars and they both have pluses and minuses. You obviuosly didnt buy a 350, how has your Mazda been. By the way i still sell 350z, But i now run another the yard the company owns. Do you own a black Rx8?

Weel than dale, I'll let u be the guinea pig before I let him loose on mine

:)

We will see what he can come up with first. How is your Rx8 going?

Yeah, got a black one, it's different from the other ones around town in that so far, it's the only one with black plates. The Z was a nice car, but after driving the 8, there was no doubt in my mind :) You're getting a black one?

Yeah im getting black. Love the colour in this car, going to lower it and have ordered 19" racing hart alloys in graphite should look good.

Hi guys. Topic please!

Cheers,
Hymee.

PS - I'm not being a prick, just the thread has gone waaaay off topic!

Hymee, is there anything from you in pipeline with regards to full exhaust system not just cat back? sorry if this has been asked before. I am in the motor industry, but no one in Canberra really has any info or have done a system for one.

Dale,

Nice way to get back on topic! :D

My "pipeline" is planning one. I will keep you all up to date, but we will have to wait until the new year.

Plan is for a mid-pipe with hi-flow cat, and a set of headers. First set will be custom made, and then jigged. Performance tested by an independant tuning shop.

Cheers,
Hymee.

Hymee,

Thanks for that look forward to seeing some results.

Cheers,
Dale.

Any update on this exhaust? Is it for sale yet? Where do you buy and any soundclips? It looks awesome. What would shipping and total be to 78641? Thanks

Leegina,

After a sucessful prototype, we made a master. It is on my car at the moment, and supposed to be coming off very soon. When we take it off, we will be able to make the jig, and then go into production. Some folk have paid deposits to help get started, for which I am most appreciative. When I get the master off my car, I will weigh it and get some quotes for US shipping. You are not the only one from the US to enquire.

Perhaps if we could organise a group buy for the US we could get a better shipping rate. I am keen to see some stateside.

There is more info on these threads, including details on a slight (but better) design mod, sound clips, and dyno charts, and more happy cutomer comments from Wildcard.

Looks tuff. Sounds nice, no drone, all what has been said before.

It also passed the noise meter test. It was 86 - 88dB at 6000RPM (3/4 RPM of Max Power). The limit is 90dB.

let me know when you have dyno it with and without it on the same condition Hymee... eager to know

Don't the dyno results linked above show this? Also, I don't recall additional power being one of Hymee's major claims, but there appears to be c.1-2 RWHP in it.

very tempting. It would be really cool if we got flames as well.

love the sound

I believe the flames are due to the tune. If you want flames, I'm sure we cam program them into a custom tune when that comes... with the relevant disclaimers etc!

Glad you like the sound. I miss the sound now. We just took it off to have the jig made. Progress!!

Taka, I posted the dyno charts, both corrected to SAE J whatever it is. That is about as close as you can get to "same conditions". If that is not what you mean, can you please clarify?

Cheers,
Hymee.

Hitman my friend, there is no doubt about you. First it’s the SS and now this.

That Les sure does nice work. (‘Though I’m not sure about you stopping him working on “real” cars.)
Makes you wonder where the “expert” custom shops get their prices from. :mad:

P.S. Can you, Les and Mark give ME flames? ;)

Sorry dudes, but no flames from the Hymee exhaust. Believe me, I tried REALLY hard to get them, but couldn't. I drove my car hard at high revs for about 15 minutes and then revved the piss out of it with a video camera at the ready, but didn't see any flames. :(

I still reckon it is the tune, not the exhaust. Remember the guys in the US got flames out of the stock exhaust when they tried hard enough.

Cheers,
Hymee.

I think you are right there Hymee. The US ECU map seems to be richer than ours, which makes flames more likely. Here is that photo of the guy in the US who got flames out of his stock exhaust.....

You need a lot of heat to produce a blue flame, that thing has no cat...!

Gomez

Hymee , When could I order one? I want the one for 350.00 plus shipping. Could you give me a quote to Leander, Tx 78641 on shipping and when one would be available for shipment. Thanks

Over a period of time, and some hard work, I have seen them get a very slight gold tinge. It is easily removed with some Autosol metal polish.

I wash mine regularly with a squirt of non-acid wheel cleaner, whenever I wash the car, and they are still "normal". It does a great gob on disolving the black soot. My system has done over 35,000 km.

Cool! Where did you order it through?

I got mine from http://www.racingbeat.com/...I am not sure if my reasoning was right in getting the one I got :rolleyes: lol.. but I was reading some threads in here :( , and what some guy's has and how they like it... but there was a poll going on in a couple of different threads on who like what. :cool: . and I saw that racing beat and greddy was almost had an accident. :D .lol so I went with racing beat :eek: .

Hi Hymee, I am interested in getting some detail about your cat back exhuast, such as price and shipping etc... I live in Sydney and I am after the cheaper one.
reply in public or private.. doesn't matter.. thankyou :)

BTW, how has your 'mid-pipe plan' been going? as all of us know, there is not much power gains without changing the mid pipe or the cat.. definately will get a high flow cat and even a whole exhuast system.. pls advise.. thx

:confused: The Hymee catback is not the Racing Beat exhaust I think your on the wrong thread.

Thanks for that. It confused me a little as well!

Having experience 1st hand both the Hymee system and the Racing Beat system, I know which one sound the best. (And looks the best IMHO).

We are doing an install of a GReddy turbo on a local RX-8 soon (~2 weeks), and at the same time making a custom 3" mandrel bent TIG welded polished stainless steel system from the turbo back. This will include an slight modification to the famous "Hymee" to take a 3" intermediate pipe.

Also giving it a "proper" tune-up by GTP.

Shhhh ;) :eek:

Details forthcoming.

Cheers,
Hymee.

Sorry dudes, but no flames from the Hymee exhaust. Believe me, I tried REALLY hard to get them, but couldn't. I drove my car hard at high revs for about 15 minutes and then revved the piss out of it with a video camera at the ready, but didn't see any flames. :(



I got flames.

That should sort out any tailgaters!! :D
