Yoshimura CRF300L/Rally 21-26 Race RS-12 Stainless Slip-On Exhaust, W/ Stainless Muffler

Elevate your adventure-ready Honda CRF300L or Rally with 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.

We didn't just build an exhaust; we crafted a revolution. Starting with the CRF300L/Rally's capable 286cc single, our 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.

• Slip-On Simplicity with Serious Punch: Not ready for a full swap? The RS-12 slip-on with spark arrestor still crushes it with up to 7.0% HP gains at 5,000 RPM and 7.5% torque boost at the same peak – perfect for quick installs and immediate gratification.

Power is pointless without practicality. The RS-12 sheds pounds to keep you agile:

• Slip-On: Slims down to 7.3 lbs (vs. stock muffler at 10 lbs), blending big-bore attitude with everyday usability.

Advanced muffler design tames roar to a refined growl, ensuring you stay under the radar (and within regs) while turning heads. Plus, every RS-12 includes our custom matte carbon fiber heat shield – sleek protection that looks as good as it performs, included with every full system or slip-on.

The RS-12 is engineered, developed and built in Chino, Ca. with quality you can trust.
