Yoshimura · AT2 · Slip-On
The Yoshimura AT2 Stainless Slip-On Exhaust is a Street Series exhaust system designed to upgrade the look and ride character of Kawasaki’s twin-cylinder platform. Built as a slip-on, it’s aimed at riders who want a cleaner, more aggressive presence along with a richer exhaust tone.
This AT2 system fits Kawasaki Ninja-400 2018–2023, Kawasaki NINJA-500 2024–2026, Kawasaki Z400 2019–2023, and Kawasaki Z500 2024. It features a carbon fiber heel guard and is designed, developed, and manufactured by Yoshimura R&D of America, Inc. in Chino, California.
Performance
As part of Yoshimura’s Street Series Exhaust System lineup, the AT2 brings a focused slip-on configuration intended to sharpen the bike’s overall presence without changing the entire exhaust system. It’s built around the AT2 series styling and targets riders who want a purposeful, performance-inspired street setup.
Engineering
Constructed from stainless, this AT2 slip-on is designed for street use where durability and consistent appearance matter. The slip-on format keeps the upgrade straightforward while delivering the distinctive character associated with Yoshimura’s AT2 approach for the Ninja and Z models listed in the fitment table.
Materials
A carbon fiber heel guard is included as part of the AT2 slip-on design, adding a premium detail where the rider’s boot and the exhaust area meet.
Fitment
Yoshimura positions the AT2 Street Series slip-on as a styling and riding-experience upgrade for the Kawasaki Ninja 500 platform and notes it as an option for the 451cc twin cylinder. The system is also stated to be compatible with the Ninja 400 and Z400, giving riders across multiple model years a consistent AT2 look and sound character in a slip-on package.
Development
Yoshimura states the AT2 is designed, developed, and manufactured in Chino, California by Yoshimura R&D of America, Inc. This background ties the system to Yoshimura’s U.S.-based development and production, aligning the AT2 Street Series slip-on with the brand’s established approach to street-focused exhaust design.
