Do I need a gasket between the cat and the exhaust? I did not have one when I remove the stock exhaust, so I installed my Comptech exhaust without one, but when I ordered the Carsound cat, it came with a 3 bolt gasket. Do I need it? I figure it would not hurt to use it, right? Thanks.

 

what size cat did you get? how do you like the comptech ss catback and what piping diameter is the catback??

 

both are 2.25"

 

i had one on mine, I think u need one tho...so nothing leaks
