yea i know that stuff, im just wondering which companies have the highest numbers that are proven on the dyno.
i want to know for sure im getting an exhaust system that has verified and true claims, as well as higher numbers than the others out there. i mean with something as far as exhaust, its fair to say some are better than others...and im looking for the exhaust that was built for max gains. |

cantc0pe,
Right now I think the highest proven exhaust is the supersprint full exhaust with downpipes. I think it posted 26RWHP. Toss in a procede with that and you will have huge numbers. at least 400rwhp and probably 450RWTQ if not more. |

How do you like it? I am interested in an ultimate racing cat-back. It seems like a middle of the road exhuast compared to others. Which is what I'm after. From the videos I've seen, it sounds perhaps like a louder version of the stock exhaust?

Not too shabby on the dyno numbers either. Good gains throughout the entire powerband with no other mods. Just bolt-on and go! Darryl www.ultimate-racing.com |

Lets see.. My 335i put down 350RWHP and 400RWTQ. With JUST procede. Someone I know has full downpipe/exhaust. He says its about 30-40hp which I wouldnt doubt. Add in a custom stage 1 procede map and 400RWHP isnt unlikely.

shiv's procede v2.0 put down 376 to the wheels thats with his cat back and 405wtq.. when i replaced my downpipe and went catless on my sti and got it tuned i gained close to 26whp more. then just stock with a tune.. and the bmw downpipes are much more restrictive then my sti's, just take a look there right off the turbos.. its like a bottleneck..
