Yoshimura RS-4D Exhaust System

The Yoshimura RS-4D full exhaust system was designed around the technology that made the RS-4 pipe incredibly successful on the racetrack. With dual internal baffles, the RS-4D muffler increases exhaust flow utilizing a unique dual-outlet design that results 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.

Nearly all Yoshimura exhaust systems that have won Motocross or Supercross championships are members of the Yoshimura Signature Series. All Signature Series pipes have been tested, documented, and marked as required by federal and state regulations. Working in conjunction with factory race teams has allowed Yoshimura to increase performance, keep sound levels to a minimum and centralize mass. The end result is a exhaust system that gives you an unparalleled competitive advantage.

Features:

  • Unique dual-outlet carbon fiber end-cap
  • Dual internal baffles for enhanced exhaust flow
  • Pentagonal-shaped sleeve
  • Polyresonant front chamber which helps reduce noise
  • Titanium header
  • Yoshimura Signature Series muffler
  • Low-volume insert included
  • 100% Made in the USA
