2009 Yamaha YZF-R1 M4 Exhaust system
Sep 8
This is a 2009 R1 with the M4 Carbon no-cat exhaust system. This was a PERFECT fit and great sound! This dyno’d in at 160hp and 77.8 torque with the flattest curve I’ve ever seen, all the way to 13,900 rpm.

lil’ flyby on a back country road. I hit 120mph, not to fast.
Got the new M4 Slip on, and this is what she sounds like. Can’t wait till its broken in more.
