Looks great. Was a fairly easy install except I don't think it is for a 2500 HD with a 6.0. I have factory 4 inch pipe and the Banks came with 3 inch. I was able to use everything from the muffler back but had to tack weld the muffler to the factory pipe off the manifold until I can buy a 4 inch to 3 inch reducer.
Makes a huge difference
My 83 F250 is way more responsive. I could barely keep up with traffic going up steep grades at highway speed. Now I can pass cars on the same grade. The instructions aren't great and some parts didn't fit right. I had to grind about an inch off the inlet flange foot to get it to fit. Overall a fun project and performs great.
