I am looking into experimenting with my exhaust.  I want to go the route of a supertrapp (or the off-brand equivalent) because I like the adjustable sound/back pressure.  My question is which one should I try first and has anyone tried something like this before?

This is an off-brand supertrapp made for volkswagens that i might be able to fit

This is the real supertrapp that I know will fit on the bike, but it will cost twice as much.
