lol.. I have a supertrapp, but its about bust.
after playing ambulance and rescue with my quad on the weekend, the baffle/internals are almost completely blowen out the end. But It got rode HARD HARD, and the supertrapp was in rough shape.
there are probably other better Tunable exhausts out there.
I just found a great site, actualy from a catalog I found at work. about 40-65% less for parts n things than I can get em for from dealers etc in town.
