Yoshimura R-77 Race Series Works Slip-On Muffler with Stainless Steel Sleeve

A unique offering from Yoshimura R&D of America. Works Finish is not a coating, but a special finish using Yoshimura's special recipe of ingredients. The result is a stainless steel exhaust that after it goes through a heat cycle on the motorcycle, takes on unique coloring that looks much like those works components our factory racers use.

If you're looking for that competitive edge, look no further than Yoshimura's Race Series exhausts. These exhaust components are designed with nothing but power in mind. Each Race Series system is developed in accordance with noise compliance regulations imposed by most race sanctioning bodies worldwide.
