    Does anyone have any experience with the Bully Dog 4" turbo back exhaust package? I've seen most systems advertised with either 3" or 3 1/2" turbo downpipes upping to the 4" exhaust pipe. Would the additional size in the downpipe be an advantage?

    I bought this truck from the original owner and it is has been maintained well, but never modified. All over the road miles cross country with a receiver hitch towed trailer.

    Within the last 6 months, its had front suspension rebuilt, new brakes, new tires, new inj pump, injectors, starter, and alternator replaced. Then he spotted a new 2009 Duramax CC DRW with a custom tow bed on it he had to have.
