Two Brothers Racing Custom-Performance Exhaust for 2009 Yamaha R-1


Two Brothers Racing announces the development and production of 2009 Yamaha R1 Cat-back dual slip-on, custom-performance exhaust system. Testing data shows this system is 3.5 pounds lighter than stock and delivers over 6 additional horsepower in the mid-range (6,200 RPM) while adding over 4 horsepower at the peak (11,700 RPM). Torque is pumped up, too. Mid-range pull is boosted by 5 foot pounds (6,100 RPM) and peak torque (8,900 RPM) is increased by nearly a full foot pound. Designed and hand-built under one roof in TBR’s California facility, the 2009 R1 Slip-on system is available in aluminum, titanium or exclusive filament-wound carbon fiber construction.
