At DMG Motorsports, we present the Yoshimura RACE R-77 Slip-On Dual Exhaust SS-CF-CF (P/N 1414020220) — a race-proven muffler system built for riders who demand real performance gains without compromising on style. Born from Yoshimura's decades of factory road racing experience, the R-77 was designed with the needs of the racer in mind, using feedback gathered directly from the Yoshimura Road Racing Team. This dual slip-on configuration pairs a stainless steel core with carbon fiber sleeves and carbon fiber end caps, delivering an aggressive, track-focused look alongside a noticeable reduction in weight over the restrictive stock exhaust system.

Every R-77 muffler is built around a trapezoidal-shaped sleeve that maximizes internal muffler volume while keeping a sleek, low-profile silhouette that flows with the lines of the bike. Inside, a straight, single-core baffle promotes superior exhaust flow for a deep, aggressive tone and measurable performance gains, while the muffler remains compatible with Yoshimura's optional low-volume sound insert for riders who want to dial back volume when needed. As a Race Series product, this exhaust is intended for closed-course competition use and is not designed for street/highway use. Each kit ships with the necessary mounting hardware for a straightforward slip-on installation over your factory header pipe.
