Hey all, bought a new Lincoln 175hd last week and decided my task would be to build the rest of my exhaust. Unfortunately, I still have the stock downpipe and a 2.5 inch magnaflow muffler. After the downpipe it transitions to a 3 inch cat, then 3 inch piping to a 2.5 muffler. I gotta reuse my muffler from my na setup till I can afford a new one. Anyways, heres some pictures, and yes my welding is horrendous. I took a class last winter and I only used a Lincoln 135 with gas, but this was all done with innershield. (Getting a tank soon) That and i've never welded "on car" before. Ok, theres my excuses.
