Yoshimura R-77 Race Dual Slip-On Exhaust with Carbon Fiber Mufflers | Kawasaki ZX-14R 2012-2025 | Closed-Course

The Yoshimura R-77 Race Dual Slip-On Exhaust is a closed-course, twin-canister bolt-on system for the 2012-2025 Kawasaki ZX-14R, featuring two trapezoidal carbon fiber mufflers, stainless steel tail-pipes, riveted 304-L polished stainless end caps, and straight single-core baffles that accept removable low-volume sound inserts.

The ZX-14R runs a dual-muffler layout from the factory, and this kit keeps that symmetry while shedding a substantial amount of the stock system's weight — the ZX-14R's OEM canisters are among the heaviest fitted to any production motorcycle. Carbon fiber sleeves over stainless internals do most of that work.

The trapezoidal R-77 profile carries far more packing material than a round canister of the same external size, so the straight-through baffles can flow freely while the system still manages sound. Both mufflers are built at Yoshimura R&D of America in Chino, California, and the kit ships with dual stainless tail-pipes, mounting hardware and instructions.

• Riveted 304-L polished stainless steel end caps
• Trapezoidal muffler profile for maximized internal packing volume
• Straight, single-core baffles; removable low-volume sound inserts available

Fits the 2012-2025 Kawasaki ZX-14R as a direct bolt-on to the stock headers, and is the standard dual-canister exhaust choice for ZX-14R drag racing, roll racing and closed-course top-speed builds.
