Yoshimura R-77 Exhaust System BMW S1000RR 2010-2011 The BMW S1000RR has made a big splash in the world of Superbike racing thanks to its immense power. We wasted no time in adapting our flagship R-77 pipe to fit this incredible machine and are now offering a Full Stainless Steel System to give S1000RR owners the ultimate in Yoshimura power. The Yoshimura R-77 is a pipe that was designed with the needs of a racer in mind. Using the feedback we received from the Yoshimura Road Racing Team, our designers came up with a muffler that is constructed from lightweight materials, grants a significant boost in power thanks to its high-flow trapezoidal shape, and gives your bike a great sound without being excessively loud. When combined with the new stainless steel full-system, the muffler will help your engine make even more power and reduce weight. We also included a carbon fiber muffler bracket which replaces the passenger foot pegs, further reducing weight. The end result is a complete exhaust system that will let your BMW S1000RR reach its maximum potential! The Yoshimura R-77 Full System includes Stainless Steel/Carbon muffler construction, Stainless Steel header and tail-pipe, Carbon Fiber muffler strap and hanger bracket, our specially designed aluminum heat-shield, a pre-installed stainless steel M18mm 02 bung and plug, detailed installation instructions, and all necessary hardware.
