The YOSHIMURA R-77 Slip-On Exhaust features a distinctive trapezoid-shape muffler designed to maximize internal volume. This structural configuration supports a straight, single core baffle, ensuring efficient gas flow while maintaining the compact profile characteristic of the R-77 series.
Engineered for versatile acoustic performance, the system incorporates a low-volume sound insert capability. This design allows riders to tailor the exhaust note to their preferences, balancing the inherent efficiency of the maximized internal volume with controlled sound output.
