At DMG Motorsports, we present the Yoshimura R-77 Street Series Slip-On Exhaust (SS-SS-CF Works Finish, PN 15350AJ521) — a race-bred muffler built for BMW G310R and G310GS riders who want a lighter, better-sounding exhaust without sacrificing durability. Yoshimura built this slip-on around its signature R-77 profile, a design proven in the heat of competition and now tuned specifically for the 310cc single-cylinder platform. The stainless steel body is finished in Yoshimura's exclusive Works Finish, which develops a unique heat-tempered coloring after its first ride, giving it the same distinctive look as the titanium components used by Yoshimura's factory race teams.

The muffler's trapezoid shape isn't just for looks — it maximizes internal volume for efficient flow and a deeper, more aggressive exhaust note, while the straight, single-core baffle keeps performance consistent and maintenance simple. For riders who want to dial in their sound, the muffler is capable of accepting a low-volume sound insert, letting you tailor the exhaust note to your preference or riding environment. A carbon fiber end cap caps off the package with a lightweight, race-inspired finish that complements the G310's sporty lines.

This slip-on is designed as a direct bolt-on for a stock-equipped G310R or G310GS and is proudly designed, developed, and built in the USA. Note that this exhaust is not CARB approved and cannot ship to California.
