Yeah Ralph, have you even heard a 919 post-bafflectomy? Pretty sure it's still quieter than any aftermarket.
I was lane splitting last week and I moved aside for another bike to go through past me. While I was trying to squeeze through cars that didn't know I was coming, he gave a little throttle and cars moved over for him. And that's me with a bafflectomy, him with with a nice (but not annoying), deep, aftermarket exhaust.
