so what? i made 16whp on my kamikaze 4-1 with testpipe on my JRSC ITR. but now since im doing all motor im running a modded smsp carsound cat.
pollution is part of life, like i said most cars at the track run open exhaust and straight pipes. do u think they are worried about pollution?? i would like for you to ask some of the NHRA mechanics to run a cat and see what they will tell you.
i could care less if u run a testpipe or a cat, ive ran both.
