The Yoshimura R-77 Exhaust offers outstanding performance, thanks to being developed in the heat of competition. It features a trapezoidal design, which allows a large volume of packing material and in turn delivers top performance with minimal sound increase. The R-77 muffler's front cap is MIG-welded, while the end cap is riveted using high-end 304-L polished stainless steel rivets and bands.
Yoshimura Works Finish is a unique offering from Yoshimura R&D of America. The Works Finish is not a coating, but a media blast finish using Yosh's own special recipe of ingredients which results in 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. This Special System is available now for Yamaha FZ-09 in Race Series full system carbon/carbon and stainless/carbon muffler options.
