I love my Thrush Welded. It's a Flowmaster clone, but I think its a little throatier. The parts number for a direct fit is 17651. It's like $38, so about half price of a Flowmaster.
92 YJ, 4.0, 5" BDS springs, 1" booms, 1" BL, 35x12.50x15 MTZ's, Ford 8.8 with LSD, 4.10 gears. It's never done though.
