I'm looking into getting a hitch and cargo carrier. The problem is I have a GMPP exhaust. and I'm not sure of the width dimention diffrence between stock and the GMPP. If anyone has a GMPP exhaust and hitch please let me know if the hitch will clear the exaust, or if someone can give me a measurement (width) of the stock exhaust. The measurement would be from the holes in the frame (over top of the muffler) to the inside edge of the muffler.
