May fit other things or hell cut it up, I have a 3" exhaust (from 2.5" header flange) into 3" cutouts then to 3" in/out flowmaster dual chambers then dump. I was going to cut up and sell the cutouts and mufflers for a total of 140-150 but I will sell it to someone for 170 if they want it.
wish i had pics of it installed before I took it down, it does really flow great and looks even. It dumps right at the axle
