3 inch pipes on a sohc? are you guys outta ur mind?

what spec is your car? i know with my cali spec..due to the 2 precats and main cat.. my car is still somewhat quiet.. even with my 3sx downpipe and custom striaght pipe cat back..

and are you looking for power or sound? because i had a tt borla 3inch catback on my car for a while..sounded nice..quieter then the 3inch on n/a dohcs(im guessing due to the cali spec) but i lost power due to no back pressure
