What to tell the exhaust shop.

On the exhaust for my truck I did mine all myself. Ever see one of those kits from summit, jets etc with all the bends you weld together yourself? I did a similar thing. I went to the local exhaust shop and raided the dumpster, found some newer stainless 2-1/4 pipe with nice mandrel bends in there, looks like they took exhaust off of something really new and put something custom in its place. Took it home and welded it up myself. I still gotta finish it, want a different muffler and still have no tailpipe yet, just had to put something on so I don't get the cops called for now while I work on it in my garage and driveway/ but it doesn't look too bad, certainly don't look cobbled at all. Total cost so far for material $0, just a little time and MIG wire.
