At DMG Motorsports, we present the Yoshimura Signature Series R-77 Dual Slip-On Exhaust (SS-CF-CF, PN 13150E0220) — a race-proven muffler upgrade built for riders who want genuine performance gains without sacrificing OEM-level fit and finish. Part of Yoshimura's Signature Series lineup, this dual slip-on is engineered so a dealer can install it with confidence, delivering the sound, look, and flow improvements Yoshimura is famous for on the track and street alike.

This R-77 muffler pairs a durable stainless steel body with sharp carbon fiber sleeve and end caps, giving your ride a lightweight, aggressive aesthetic to match its improved performance character. Constructed with a trapezoidal shape, the design maximizes internal packing volume so you get top-end performance with minimal increase in sound. A straight, single-core baffle promotes ample, efficient exhaust flow, while the front cap is MIG-welded and the end cap is riveted using premium 304-L polished stainless steel hardware for a clean, long-lasting fit.
