Got my BKuzzy today and all installed. Man is this a wild exhaust. It's rather heavy but you can't beat the quality. Welds are beautiful to say the least. The end tip on this exhaust is HUGE 2 5/64" and I'd guess the core is 2" or a little larger. I'll tell you what there is nothing quiet about this exhaust. Very loud sounds like it's pissed off lol. Anyway big thanks to Neal (G-rider) (I bought it from him) Hell of a guy to deal with. Here is a picture and a video.
