Yoshimura – RS-12 Signature Full System (Honda)

After years of development and testing with Yoshimura’s factory race teams, the RS-12 Signature Full System brings true race-proven innovation to your Honda. Every detail of this exhaust has been carefully designed for maximum power, minimal weight, and unmatched precision — from the asymmetric muffler shape to the hand-crafted carbon fiber end cap. The result is a system that not only performs like a factory setup but looks the part too.

The RS-12’s asymmetrical tapered design increases muffler volume for improved sound management and power while maintaining clearance for the tire and brake caliper. The tapered inlet allows the system to be mounted closer to the engine, helping centralize mass and improve handling. A patent-pending Precision Taper Fit (PTF) insert ring makes removing or installing sound inserts and spark arrestors simple and secure. The matte carbon fiber end cap features Yoshimura’s signature detailing, blending aggressive style with pure function. Every component is made and assembled in the USA, ensuring top-tier quality and fit.

Why We Like It:
It’s the kind of exhaust that transforms your Honda into a race-ready machine. The RS-12 feels smooth, strong, and responsive — with a deep, clean exhaust note that sounds as refined as it performs. You can tell it’s built by people who actually race.

Why It’ll Work for You:
This system helps your bike make more usable power across the entire rpm range while shedding weight and improving balance. The clever muffler design reduces noise without killing performance, and the carbon fiber finish looks as good as it performs. It’s easy to maintain, simple to install, and engineered for riders who want true performance gains — not just sound.

Available for modern Honda motocross and off-road models. Optional inserts and spark arrestors sold separately.
