CRF250L\'12-16 - Yoshimura RS-4 SS Full Exhaust System

The work that went into developing the RS-4 muffler has paid big dividends in Off-road Racing; winning multiple Supercross and Motocross titles since it's inception. We've developed the current generation RS-4 based on that research & development, and the result is a unique design that provides an unrivaled combination of power and quiet exhaust tone. The RS-4 features a Polyresonant duplex chamber and two-staged stepped baffle for increased performance, while a carbon cone end cap finishes off its innovative styling.

  • Pentagonal-shaped sleeve
  • Front muffler cap functions as a polyresonant chamber which helps reduce noise
  • Laser-cut heat shield on polyresonant chamber
  • Two-stage stepped baffle
  • Turn-out carbon fiber end-cap
  • Stainless steel header and tail-pipe
