Hey guys- got my hands on a Yoshimura R-11 slip-on. Install was hella easy- one bolt holding the clamp and one bolt securing the can to the right passenger peg. The note is very grumbly and throaty at low RPMs and is relatively quiet when cruising at mid-range RPMs. The video does not do the pipe justice as the sound gets blown out, I'll have a flyby video up in the coming days.

I love mine, I added the K&N air filter , did the air box mod and added the Bazzaz ECU controller with preset map for my pipe and filter. Played with the gearing , hah what an improvement almost 120 hp , will be on the dyno this spring and can give the actual numbers. The Bazzaz is the key to unleashing the HP in this bike. I can tell you though my buddy with his new GSXR 600 isn't very happy with me now.
