The Yoshimura R-77 Exhaust System was designed with the needs of the racer in mind. Using the feedback received from the Yoshimura Road Racing Team, their 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 stainless steel headers and mid-pipes, the muffler will help your engine make even more power and reduce weight. The end result is a complete exhaust system that will let your motorcycle reach its maximum potential!
