A couple of weeks back I'd decided that I wanted to make my bike sound like the super sic crossplane mofo that it was born to be, like the Yamaha MotoGP M1 that had spawned this super sexy machine. I had finally ordered an after market exhaust for my new R1. Well today I got my new Yoshimura 3/4 system from the nice people at MCAS. So this is what it looks like.
