RX-8 aftermarket exhausts SUMMARY

OK, here is what I have found so far, all in one place.

First, the sound of a stock RX-8 -- click here



Second, "Header-back" systems -- these are NOT street-legal:

Greddy: Price is about $1000 for complete system.
Greddy claims a 22HP increase over stock for this.
Click here for info

B&B: Price is about $950 for the cat-back system plus the race pipe.
Vivid Racing claims a 19 HP increase over stock (unknown if this is with or w/o cat).
Click here for info
Click here for video clip


Third, Street-legal systems with cat. If the info isn't there, I didn't find it. If anyone has any more info on an exhaust system for the RX-8 please e-mail me at [email protected] and I will add it to this post. That way we keep all the exhaust info in one place.


On to the exhaust systems!

Is this the manufacturer's claim or data from a test? If it's the manufacturer's claim I can list it as such; if it is from a test, I'll list it as soon as I see the test data.
Thanks for the info.

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.

Get your butt over to my shop and let us put our exhaust on your car. Free dyno time for you also and exhaust at cost. If you dont like it I will take it back and you can have one of the others at my cost. You cant beat that :D

Cool Its what is down-under that counts!

Hi guys,

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

We have produced the first "Hymee Exhaust - Stage 1" Catback

Please see the following thread for some more pics and reviews including sound opinions:

https://www.rx8club.com/showthread.p...threadid=16734

Cheers,
Hymee.

PS - $850 Australian is about 630USD.

Hey guys I was wondering what happens to your warrnty after you put on an aftermarket exhaust and intake system. Besides just taking it off and putting it back on. Does an aftermarket exhaust only void your exhaust warrnty? Any answers will be greatly appreciated thanks.

You got it... it only voids your exhaust warranty. See this thread for more info.

No. If I had it, it would already be added to the first message of this thread. If anyone has any exhaust clips they want to add, just e-mail me about them -- my e-mail address is in my profile. I can put them on my server and link to them here.

Failure to Elucidate

Definition

The definition is harder to understand than the term being defined.

Examples
(i) Someone is lascivious if and only if he is wanton.
(The term being defined is "lascivious". But the meaning of the term "wanton" is just as obscure as the term "lascivious". So this definition fails to elucidate.)
(ii) An object is beautiful if and only if it is aesthetically successful.
(The term "aesthetically successful" is harder to understand than the term "beautiful".


Proof

Identify the term being defined. Identify the conditions in the definition. Show that the conditions are no more clearly defined than the term being defined.
