The factory Jeep Wrangler exhaust is positioned too low, and is susceptible to damage. In addition, the cross over pipe is in a poor location, and can easily be damaged by rock, and when braking over a steep rise or berm.

I had a custom exhaust built using a small turbo muffler 2" x 6" x 10", and had the exhaust routed higher than stock. I also had the shop install two extra mounts. The system is tight, rattle free, and offers great clearance. The only negative was a slight drop in top end power. However, the torque band dropped slightly, which I considered a better outcome anyway.
