The all new R-77D muffler has been developed throughout years of racing efforts, and hours of meticulous research and development by Yoshimura engineers. It's distinctive dual outlet end-cap design puts an enticing twist on the style of the original R-77, and further increases the mufflers open outlet area, resulting in increased exhaust flow while maintaining moderate decibel levels.
3/4 systems include the R-77D muffler, stainless steel mid-pipe, a Yoshimura under-belly muffler to replace the bulky stock unit, and all necessary hardware for installation.
