Yoshimura Race R-77 Slip-On Exhaust | Kawasaki ZX-14R 2012-2023 | SS/CF Dual

Upgrade your ride with the Yoshimura Race R-77 Slip-On Exhaust — a dual-outlet system built from premium stainless steel and carbon fiber. Engineered for riders who demand real performance gains without sacrificing street presence.

The signature trapezoid-shaped muffler maximizes internal volume for improved exhaust scavenging and optimized engine efficiency. A straight, single-core baffle delivers a smooth, consistent exhaust pathway for enhanced throttle response and power output. The included low-volume sound insert lets you dial in noise levels to match your riding environment — track or street.

Bolt-on installation makes this one of the cleanest performance upgrades available for your motorcycle.
