The Spintech exhaust one wouldnt come up. Does anybody know where i can here a clip of this one at? What about the exoticspeed exhaust. How is it, what are the nunmbers, and is any good?
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).

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 bob@bobclevenger.com and I will add it to this post. That way we keep all the exhaust info in one place.

Yeah, but a 1G is OBDI and isn't a very big feat not to have the CEL come on with no cat. OBDII monitors this a lot closer though. I think it has a lot to do with the turbo.
Ignore any claims of HP increase from the exhaust on a stock 8. If you remove the exhaust entirely you would only get ~5 HP. The only way you would be able to get more than that would be to gut your cat or replace it with a midpipe. Either of those options means you'll fail any emissions testing and your car will almost certainly throw a CEL. But you will feel the difference so plenty of people have 'em.

Thanks for the info man. I am about to order the B&B exhaust, I was wondering if anyone had anything good/bad to say about it

I call BS on this.
My REV8 Racing Beat catback and Mazsport midpipe netted me 40 extra horsepower.
I do have a supercharger, a non supercharged car would get a little less than half that.
Removing the cat gets more horsepower on almost any make and model of car.
The REV8 with the standard cat gives about 5-10 HP on a N/A RX8 or 10 to 20 on a S/C RX8

Racing Beat disagrees with you:
http://www.racingbeat.com/resultset....rtnumber=16397
Stock production engine - with muffler removed +5 HP
Stock production engine - with RB muffler + 3.5 HP
Stock production engine - with aftermarket system "A" muffler + 3.5 HP
Stock production engine - with aftermarket system "B" muffler + -1.5 HP
When someone is talking adding just an exhaust to a N/A car it's a bad idea to give them the impression that they're going to get a significant performance upgrade if they go with an aftermarket exhaust. It's also a bad idea to combine to mods (midpipe & exhaust) and then make assumptions on which is giving you the power gains you're seeing. All the dyno tests I've seen posted have indicated a (relatively for the rx8) significant increase in HP with the midpipe regardless of a aftermarket exhaust or stock exhaust. I haven't seen too many dynos testing the stock and an aftermarket exhaust on a car with a midpipe but would love to see how much more gains you get from the different aftermarket exhausts once the big restrictor on airflow, the cat, is removed.

Is the cat and midpipe the same? If I remember right reading somewhere that if the cat was replaced with a test pipse or whatever, then the ecu would have to be modded, if not the the injectors would pump more fuel and make the car run to rich or lean and it would damage the seals. Is this true?

Anyone know where I can purchase the B&B exhaust that is stated in the original post?
I was looking for a good HP gain but didn't know if I need to buy more than just the B&B Catback Exhaust System listed here. In the description it talks about additional race pipes? Is this talking about with a high flow cat or something?

Where can I purchase a Borla exhaust kit for a 07 MT?
There website only has them up to 06, I've looked on ebay etc.... nothing.
Or I would go with an HKS system, again, cannot find anything on any website.
Any suggestions?

Sounds a whole lot like a Borla tho.
Not sure if you already got your Borla but there's no changes between '04 and '08 for the exhausts (pretty sure no changes for the '09 as well but I'd wait for someone with an '09 to try it out).
