wouldnt u wanna keep it stock .. alot of people are forgeting thats its a import.. theres gotta be enough back pressure if u do change it keep me posted with results.. going with short headers from hurrican an stock converter with 2 1/2 cat back sounds an performes nice

Billy, if you would read the v6 faq, then you would see that engines need no backpressure, it is exhaust velocity that is needed, a larger diameter pipe allows more volume of gas to exit, but lowers the exhaust velocity.
