I'd like to add that yesterday I just received my Ti-Force Sumo pipe yesterday (Thanks Street and Track).. The pipe looks absolutely great and I can't wait to get it installed along with other goodies. If anyone wants pics of the Ti-Force pipe, let me know. My brother has an 01 Busa with a Muzzy. He likes the look and sound of the pipe and says there's a noticable difference in performance. I think that's going to be the case with exhaust that you mount up.
