my old mans gettin a 350 tomm and i thought it would be nice to slap an exhaust on for him. whats a good exhaust out there? i would like to keep the stock piping to swap just in case he needs to take her in for warranty work or whatever. we own a trucking company and have 7" and 8" stacks on our petes and just run straight pipes pretty much... i dont know much about pickup diesels. would straight pipe make for turbo lag? would turbo back be better then just a plain catback? thanks in advance for the help. :beer:
