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.

Edward R. ★★★★★

I was a bit worried about installation, but the stainless muffler brackets lined up perfectly with the stock hanger points, making it a straightforward swap. The sound is deep and aggressive without being obnoxiously loud on the highway.

Leo V. ★★★★★

The mid-range punch feels noticeably sharper than stock, and the stainless muffler has that deep, aggressive tone without being obnoxious on the highway. I’ve put about 400 miles on it since the swap, and the fitment on my 2021 ZX-10R was spot-on with no rattles.

Nicholas ★★★★★

Installing it was straightforward with the included hardware, and the weight savings over stock are immediately noticeable. The stainless muffler has a clean, industrial look that matches the bike’s aggressive stance.
