I made up my own tubing bender to build Dune Buggy Cages out of 1 1/2" .090 ths wall steel tubing. Other guys were using the Exhaust Pipe Bending Machines but they were crushing the inside corners. I made my own jig and dies ( 1" and 1 1/2" dies), the trick was to get it to stretch the pipe on the outside of the radius without crushing the tube, took some doing to figure that out. Not sure the same approach will work with 2" thin wall exhaust tubing.
