My exhaust goes down, makes a 90 and out under the compartment. It is the lowest spot on the whole rig and since we are always going off pavement on gravel, beach roads, I was thinking of possibly going forward through the wall, making a 90 and then installing the muffler and pipe and then out just in front of the compartment where they could never rub against the ground. The stock muffler is a little loud so thought I would also replace it at the same time. Anyone out there done this before?
