Introducing our AT2 3/4 system for 2021 Kawasaki ZX-10R and RR sport bikes.

The updated ZX-10 received electronics and emissions updates to the revised engine for 2021, while maintaining that traditional butt-kicking adrenaline throughout the machine

The stock header on the ZX-10 is hard to beat, made of titanium, it performs very well for a stock unit, so our engineers focused on where they could make the most gains. It seemed perfect to develop not an entire system, but a 3/4 Race Series system.

Our AT2 styling and performance is perfect for Kawasaki’s newest liter bike. Dripping with looks and performance the AT2 woke up the 998cc inline four cylinder engine like you would expect. Enhancing the max HP a whopping 10.4% and torque an additional 7.7% throughout the entire spectrum too! If you’re racing, split seconds can win races. The AT2 is here optimize performance and to help you win!

Substantial weight savings were achieved as well. The AT2 3/4 system drops over 8 pounds over the stock muffler while providing that insane Yoshimura AT2 exhaust note. Let’s go racing!

The AT2 is proudly developed, designed and made in the USA.
