At DMG Motorsports, we present the Yoshimura RS-12 Race Series Full Stainless Exhaust System (SKU 961-9453 / Yoshimura P/N 116610S521) — a complete stainless steel header-to-muffler system built specifically for the Suzuki DR-Z platform. This system carries Yoshimura's signature Works Finish and a striking matte carbon fiber end cap with an all-new faceted design, giving your bike an unmistakable race-bred look while delivering real dyno-proven gains. Every RS-12 is designed, developed, and manufactured in the USA, backed by decades of Yoshimura's factory racing pedigree.

Engineered around the updated fuel-injected DR-Z platform, this full system is built to unlock more power everywhere in the rev range while shedding significant weight over the stock setup. Engineered specifically for the updated 398cc fuel-injected platform, this system delivers 5.5% more horsepower at 6,640 RPM and a 2.8% torque gain at 5,180 RPM—with the spark arrestor installed. The RS-12 full system sheds over 7 lbs compared to stock, bringing total weight down to just 10.6 lbs, helping improve throttle response and handling. A USFS-approved spark arrestor (SA-21-K) and a custom stainless Yoshimura heat shield are included, making this system ready for aggressive trail use.
