i have no cat and its loud

most people lose perfomance from it. Get a high flow one, or a straight pipe. It kills exhaust efficiency.

im taking off my Broken R/T cat, and am putting in a race pipe.

Mikes car sounds bad ass with the race pipe

 

[Kyle]

My exhaust sounds perdy.


I thought your emmissions was OBD-II only? If so, and as long as you get rid of the rear O2 code, you are set.

code deletion is no prob, but when they hear my car i think they'll get curious and look.

i mean i'll have headers soon + already have exhaust and my cam is kinda rough so i dunno how they'll take that.

J/O did you pass with no cat?

If horist can pass with his T/A, I think anyone can pass. :lolsign:

A 400 cell cat....Cats dont really degrade performance given the right application and correct function and condition...

You need to be cautious on aftermarket cats. As Justin indicated, they can still set an SES if the volume of gas doesnt chime with what the post cat 02 is looking for. Hence a simulater is in order in some applications.

Too me. If your useing a sim or PCM delete, you might as well not use a cat...

alright i'll think i'll end up having it straight piped when i get the headers welded.
