>SuperTrapps have
the advantage of being tunable, that is, you can add or subtract
baffles from the exit of the muffler (which is the tailpipe) to move
the torque peak a few hundred RPM up or down the rev range.

SuperTrapp now makes an enclosed model wherein you must remove the outer 
housingto disk about.  The advantage is that you get a real tailpipe.  Works in 
a Europa!
