I cut out the resonator and muffler and put a 40 series flowmaster, single inlet dual outlet, where the resonator was. It eliminated the chance of destroying the muffler while wheeling. I custom bent the tailpipes so both pipes go over the rear in the stock location and then they split and come out the bumper. The sound is awesome, some drone but sound awesome for a 3.7L. I also put several extra braces and braced the pipes to each other because I wheel the H3.
