Yoshimura HONDA CRF250R Signature RS-4D FS Ti-TI-CF

Titanium Header / Titanium Muffler / Carbon Fiber End-Cap

When it comes to exhaust systems designed for competition, Yoshimura and the Team Yoshimura Suzuki race team have always worked toward a single goal: helping you win. A perfect example of the result of our single-minded focus is the RS-4D muffler. It builds on the technology that made the RS-4 incredibly successful on the racetrack and enhances its exceptional performance.


The RS-4D boasts a unique dual-outlet design that increases the amount of open area at the exhaust outlet. With dual internal baffles, the RS-4D increases the exhaust gas flow rate, resulting in smoother power delivery and increased throttle control. It also offers increased horsepower and torque throughout the power curve, especially in the bottom- to mid-RPM range where riders need it most.

  • Unique dual-outlet carbon fiber end-cap
  • Dual internal baffles for more exhaust flow
  • Pentagonal-shaped sleeve
  • Front muffler cap functions as a polyresonant chamber which helps reduce noise
  • Titanium header and tail-pipe
  • Low-volume inserts included
