       Home > Dual Sport > Honda CRF300L > Yoshimura RS-12 Full Exhaust System Elevate your adventure-ready Honda CRF300L or Rally with the new Yoshimura RS-12 Race Series Exhaust System – the ultimate upgrade for riders who demand more power, less weight, and distinctive sound. Born from relentless engineering in Chino, California, and tested by CRF expert Ari Henning, this Race Series beast transforms your dual-sport machine into a precision-tuned powerhouse. Hit the trails, with confidence – the RS-12 delivers on every front. Yoshimura didn't just build an exhaust system, they crafted a revolution. Starting with the CRF300L/Rally's capable 286cc single, their RS-12 unlocks hidden potential with a Yoshimura exhaust note that pleases the ear, with weight reduction, and dyno-proven results that everyone can enjoy. And it's proudly made in the USA! INCLUDED: A USFS approved spark arrestor SA-20-K comes pre-installed in the RS-12 muffler. Power: Bolt on the complete RS-12 for up to 6.8% more horsepower at 8,520 RPM and 4.3% additional torque at 6,600 RPM – all while running a spark arrestor for compliant, trail-legal riding. Feel the surge in every throttle twist, from low-end grunt to high-rev sing! Weight: A featherweight 9 lbs (vs. stock 12.3 lbs) – that's over 3 lbs saved for sharper handling and effortless flicks. Fitment: Specifications: Tuning: When installing an aftermarket exhaust on your CRF300L, we also recommend the bike be properly tuned, with either an ECU flash or an aftermarket Electronic Fuel Injection (EFI) controller, both of which will make the bike run properly with the aftermarket exhaust system. If you don't tune the bike, you will not see the full potential of your new exhaust. Plus, it may cause the bike to run poorly, and could also run hot, which is not good for the bike/exhaust over time. We currently offer the following tuning products for the CRF300L / Rally (click links below): ** NOTE: Will not fit 2025+ models, Honda changed the injector connector.
