Easiest for me was simply to put on a smaller muffler than stock. In some cases, I guess that might not be feasible- wanting to enlarge the storage tub, etc....but for me, I just wanted to get it out of the way of rocks/ boulders.
My Flowmaster Hushpower II is still in the stock location now, but is completely hidden and not in the least vulnerable to damage.
If you relocate in-line, than a Cherry Bomb Glasspack or DynoMax Ultra-Flo SS might be worth looking into.
