with hard use over time you basically end up blowing the packing out of the exhaust, ours is repackable, suspersprint is not
the sections where the exhaust clamps together aren't the best
plus the supersprint has various "hot spot" locations due to the gas flow not being smooth (the roof of the box is a good example, due to the angle its positioned at all the exhaust gas wacks the top of the box, you can tell by the fact that the fucker is BLUE!)
we've got side by side pics somewhere of ours compared to the suspersprint, shows the problems of the SS quite well
