Yoshimura R-77 Race Dual Slip-On Exhaust with Stainless 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 304-L stainless steel mufflers with carbon fiber end caps, stainless tail-pipes and straight single-core baffles that accept removable low-volume 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 OEM canisters are among the heaviest fitted to any production motorcycle. This is the all-stainless version, more durable than the carbon-sleeved alternative and the sensible choice for a bike that gets ridden hard on the road.

The trapezoidal R-77 profile carries far more packing material than a round canister of the same external size, so the straight-through baffles flow freely while the system still manages sound. Both mufflers are built at Yoshimura R&D of America in Chino, California.
