Thats the one I want. Your bike looks great. And the M4 exhaust sounds awesome. Once I pick up my Gen 2 I plan to do the same exhaust set up. I will most likely do away with the dual exhaust. My gen 1 has dual megaphones and it is probably one of the loudest bikes you will ever hear. Its rediculous loud lol.
I love the M4 on the Busa. Great deep tone. I wanted some good volume but not quite into the ridiculous level... I wanted to keep the friendly relationship w/ my neighbors when I leave every morning. Trust me though, dual M4's with baffles out is plenty loud.
