m4 baffles

  1. FZ-09 General Discussion
    Just recieved my stage 2 quiet baffle for m4 Havnt been able to find a single thing about it on the interenet for our bikes just for the m4 moto gp style exhaust. Wanted to let you guys know it works great. Quiets it down abit more than regular baffle it comes with. Its still loud but doesnt pop...
