Yoshimura · AT2 · Full System
The Yoshimura AT2 Stainless Full Exhaust is a Race Series full system built to bring the Kawasaki Ninja 500 to the track with a purpose-driven setup. Designed for Kawasaki NINJA-500 2024–2026 and Kawasaki Z500 2024 (see fitment table below), this system pairs Yoshimura’s AT2 design with stainless construction for a complete replacement from the engine back.
This full system includes a carbon fiber heal guard and a low volume sound insert INS-20-K, making it a smart option for noise sensitive race tracks. A dyno chart, product video, and installation PDF are available on the page for additional detail.
Materials
Built as a complete Full System, this AT2 exhaust replaces the entire exhaust path as a single engineered package. Stainless material is specified for the system, matching the AT2 Race Series intent for riders setting up a Kawasaki Ninja 500 or Z500 for focused performance riding.
Sound
The AT2 Race Series full system includes a low volume sound insert, identified as INS-20-K. That included insert supports setups intended for noise sensitive race tracks, helping riders tailor the exhaust output to meet venue requirements without changing to a different system.
Included
Yoshimura includes a carbon fiber heal guard with this AT2 system. It adds a protective barrier in a key contact area, complementing the race-focused design of the full exhaust and helping manage rider contact near the exhaust during track and spirited street use.
Development
Developed as part of Yoshimura’s Race Series Exhaust System line, the AT2 is presented as a track-ready solution for the Kawasaki Ninja 500 platform. The manufacturer positions this Works Finish full system as a purpose-built upgrade aimed at riders who want to take the Ninja 500 to the race track with an exhaust designed around that mission.
Installation
This AT2 Stainless full system is listed for Kawasaki NINJA-500 2024–2026 and Kawasaki Z500 2024, with exact applications shown in the fitment table on the page. For added confidence before installation, the page also provides an installation PDF along with a product video, helping riders review key details prior to fitting the system.
Performance
Yoshimura states that the AT2 is designed, developed and manufactured in Chino, California. That end-to-end involvement supports consistent product execution from development through production, aligned with Yoshimura’s long-standing approach to building performance exhaust systems in-house.
