6. Yoshimura R-77D Slip-on Carbon Muffler – $599
Constructed of lightweight carbon fiber, Yoshimura’s R-77D slip-on muffler system includes a stainless steel mid-pipe and all the necessary hardware for installation. The R-77D muffler is distinguished by its dual outlet end-cap design. Yosh claims the design increases exhaust flow while moderating decibel levels. And it’s Yoshimura’s efforts in working with the EPA to offer noise-compliant exhaust systems that impresses us. We visited the Yoshimura plant earlier this year and were given a tour of its interior and all the goings-on within. So kudos to Yosh for tamping motorcycle exhaust noise while still building exciting products to help quell the threat of increased legislation from motorcycle noise opponents hell bent on homogenizing the world in which we live.
