Love the way your bike looks dude, but personally I like my vmax a little louder. Have you looked at a Kerker 4-2-1? That would still give you the horses and the backpressure you'd need but make your max really howl when you let it run. I currently have supertrapp slip ons, fully open, and it's chugs in idle. Your max looks and runs mean, I think it should sound mean too!
