after looking at the jemco I realized that it's only a 5 peice pipe(single stage divergent) and is super simple. Here's a couple pics of the pipe I made.
This one is a 7 peice not including the ton of relief cuts(three stage divergent). I want someone to measure their Jemco's dimensions(across the top and bottom) and shoot them to me. There's no reason for THAT pipe to cost $200+.
