Truthfully I've never paid 2 much attention to the booty-- I've focused a lot on the face.. But I feel like any bike with an undertail exhaust is sexy. The side pipes just look like they're "in the way" to me.
i hate my 07 tail light UNDER the exhaust. But i'm looking at the two brothers pipe and that seems to clean up the tail very nicely. I just don't like the idea of anything hanging down on the rear end.
