Yoshimura AT2 Street 3/4 Stainless Slip-On Exhaust | Kawasaki Ninja ZX-6R / ZX-6R ABS 2019-2025 | Street Legal

The Yoshimura AT2 Street 3/4 Stainless Slip-On Exhaust is a street-legal three-quarter system for the 2019-2025 Kawasaki Ninja ZX-6R and ZX-6R ABS, replacing the mid-pipe and muffler with stainless steel components in Yoshimura's exclusive Works Finish, topped with an all-new faceted matte carbon fiber end cap and a model-specific carbon fiber heel guard.

A three-quarter system sits between a slip-on and a full system: it replaces more of the stock exhaust than a canister swap alone, so it removes more weight and more restriction, but it retains the catalytic converter. That is the whole point here — because the CAT stays in place, the system does not tamper with the bike's emissions control equipment, and it remains street legal.

The Works Finish is Yoshimura's signature: rather than a fixed coating, it develops its colour through the system's first heat cycles on the motorcycle, ending up close in appearance to the titanium works components on the company's factory race bikes. Installation is bolt-on with no ECU remapping required.
