At DMG Motorsports, we present the Yoshimura AT2 Race FS SS/SS/CF WF Full Exhaust System (13320AP521) — a race-bred, full stainless steel system engineered specifically for the Yamaha YZF-R3. Built by Yoshimura's Research and Development team, this system replaces the entire stock exhaust from header to tailpipe and is finished with Yoshimura's exclusive Works Finish for a look and durability that's second to none. Riders can expect a meaningful jump in performance, with Yoshimura reporting a 9.1% max horsepower gain and a 3.7% max torque gain, along with a substantial 9.6-pound weight reduction compared to the stock OEM system. As a true Race Series product, this AT2 system is built for closed-course competition and is not intended for street use, making it a top choice for club racers and track-day enthusiasts looking to unlock the full potential of their R3.
