M4 YA9944 Street Slayer Slip-on Exhaust, Carbon Fiber is made specifically for Yamaha YZF-R6 (2015-current)

Bolt On/Slip Ons: These systems utilize the stock header assembly. Bolt on and slip ons replace the stock restricted muffler resulting in better sound and an increase in power. The ultimate slip on for the new R1. All titanium tubing to eliminate the catalytic converter with M4?s MC36 style carbon canister. Removes 14.5 lbs over stock and produces a wicked exhaust note.

Note: This system may drag during track use at heavy lean angle. M4 Recommends re-flashing your stock ECU to unleash the full potential of all M4 products on the 2015 Yamaha R1.

Note: Does not meet CARB (California Air Resources Board) emissions standards. For "Competition" use only
