Yamaha’s R1 has caused quite a stir since its introduction. If you thought people were impressed with the bike before, wait until they see it with a Two Brothers Racing exhaust system installed on it. Our Dual system will reduce weight by almost 4 lbs, add 6.3 horse power @ 6200 RPM and +5 ft. lbs. of torque @ 6100 RPM.  Overall you increase torque & horsepower and dress up the look of your bike with this dual canister slip-on high performance exhaust system exclusively from Two Brothers Racing.

Designed and built with painstaking care and attention to detail, Two Brothers Racing is proud to release our Dual M-2 Slip-on exhaust system for the new 2009 Yamaha R1, available with either aluminum, titanium or high-temp carbon fiber canisters.
