market place is a good idea i always forget about that. and i do plan on getting a gti exhaust i'm a fan of the dualies. just wanna skip the stock step and get a catback and work my way up to the headerAgreed just watch the market place and check out the for sale forums on vortex. They usually have alot of stuff too. Or you could always go the gti exhaust route and find someone that has a stocker they want to get rid of and then upgrade from there.
