1. Love mine (with the optional baffle)
This thing sounds FANTASTIC but it's simply too loud to be around people without the baffle installed, do yourself a favor and order one if you will be riding anywhere around other people.
That said, this is a fantastic exhaust and an install tip, use some high temp anti-seeze between the midpipe and silencer - the fit was too tight on mine without it and I struggled for a half hour before going that route, with great results.
