Getting the underside wrapped up, my nephew had supplied me with a pair of dirt track mufflers on a 3" headpipe with a handful of bends that was installed under some car and I had a few little pieces from some other build. It was decently made with really nice smooth bends so it was up to me to break humpty dumpty apart and piece it back together again,

I cut a muffler off with part of a bend and it became the outlet, cut the other muffler out and matched the down pipe, now I am starting with a matched pair to build the rest of the system. I built the driver side choosing within my inventory of bends, then used the remaining bits for the pass side. they are a bit different from side to side since I had to use what was remaining and the crossmember on the pass side needed a soft double curve for clearance.
