Dumping the exhaust behind the rear axle?

If you show up at a car show or cruise in a gravel lot or field get ready for a bunch of pissed off people when you idle through. I had a Duster that dumped in front of the axle and we went to a cruise one night and by the time I got it parked(4 speed, manual steering)I had totally dusted everybodies nice clean ride. Needless to say I wasn't real popular that night. The vibrations from the exhaust sometimes had a tendency to blow out my tail light bulbs.
