hey guys i have a stillen y pipe, stock cat, and stillen cat back. If i replace the stock cat with a test pipe or hi flow cat, will it be alot louder? And will it be ricy ? Does any1 have a video clip of stillen y-pipe, test pipe, and stillen catback ?

 

Well, since the stillen catback is already pretty raspy and ricey sounding I guess you have nothing to worry about. The difference will not be noticeable from my experience. Any reason why you want a test pipe besides killing trees?

 

Killing trees?

well, my stock cat is pretty rusty, i just want to know whether it will be alot louder... i kno ther is no performance gain.

 

Rusty on the outside? And? The shell of the cat converter is a good 1/4 thick. Your car will spontaneously combust before the cat converter rusts through. If it's busted on the inside then go with something from warpspeed. No test pipes.

Any reason for that reply?
