you know work rally is rebuilding stock exhausts to increase power without the noise. check them out at www.worksrally.com

 

actually, i knew about that one.... but i wouldn't want to get that one because it doesn't alter the piping, just gut the muffler. not a bad idea, but i'm looking for a 3" catback.

 

Tak555, Yeah thats the only down side of the exhaust, you a metal plate on top of the exhaust arche because the JDM exhausts are usually shorter than the USDM ones.

 

I have a Gt fabrications prototype on my dads evo. Sounds exactly like STOCK!

 

Does anyone know the hp/tq increase for the fujitsubo exhaust alone ?
A dyno chart for that will be usefull.

Thanks.

 

I'm pretty close to trading my Greddy Ti for something alittle quiter but its soo damn nice and light.

 

Fujitsubo makes I think 10hp more than stock and 7lbs TQ

I just had my entire exhaust done from the o2 housing back.. I used the helix o2 housing and DP and the RsR exhaust. The RsR appears like a straight pipe.. one would expect it to be insanely loud, but in all honesty it is not loud at all with the silencer in. When driving you can barely hear it, its a little loud at startup.. but when its warm up, it just sounds very aggressive from the back, but could be that much louder then stock. You can hardly hear anything from inside the car because the piping on it is very thick.. its not thin walled as it isnt a very light weight exhaust. Now with the silencer out its insanely loud however.
