I have been thinking of putting the underbody exhaust. I really like the looks but I have heard bad reviews on loss of power. I came across one of your threads with a pic of the exhaust. I am certain if you lost power you wouldnt be rolling with it, so I was wondering what kind of exhaust is it, and do you feel the same way about it. By the way I ride an 05 r1. Thanks for your time. Safe riding.
