At DMG Motorsports, we present the Yoshimura AT2 3/4 Race Series Exhaust System (SS/CF) — part number 14183CP520 — engineered specifically for the Kawasaki ZX-10R and ZX-10RR. Born as a close cousin to Yoshimura's Alpha Taper muffler, the AT2 blends aggressive new styling with proven race-bred performance, giving your liter bike an unmistakable edge on the street or the track. Yoshimura's engineers focused their development on the areas where real gains could be found, resulting in a 3/4 Race Series system that wakes up the 998cc inline-four with a serious jump in both horsepower and torque while shedding significant weight over the stock muffler.

Finished in stainless steel with a striking matte carbon fiber end cap and heel guard, this system doesn't just perform — it looks the part too. Every AT2 is proudly designed, developed, and manufactured in the USA, carrying forward Yoshimura's decades of racing heritage into a slip-on system that's ready to help you shave lap times and turn heads.
