Who on here has a true 4" turbo back exhaust. i went to the exhaust shop today they said 275 for 4" dp and piping back to the cab but they will still use my stock elbow. i would like the new one to bolt right up to the turbo and not the elbow.

Might have to order one from a diesel shop. Most exhaust shops are not equipped to make mandrel bends. They would most likely only have a push bender. My exhaust is from Bully Dog and is 4 inch off the turbo. At least it was till I changed turbos.

There is no point in going to a "true" 4" downpipe with the stock turbo IMO. The backing plate would still have an outlet that is 3"...
