Hello Everyone. I just purchased an 04 F350. This is the first diesel pickup I have owned. I am familiar with the Dirtymax and Cummins but have no clue when it comes to the powerstroke. From what I have heard, the head gasket is a major problem among many others. Basically, I want to do some preventative mods. I am looking for some suggestions on exhaust, programmers I live in ny and inspections are very thorough.
