Yoshimura RS-4 Comp-Series Full System - SS-SS-CF

Stainless Steel Header / Stainless Steel Muffler / Carbon Fiber End-Cap

The work that went into developing the RS-4 muffler design paid big dividends in 2010 with Ryan Dungey winning the AMA 450 Supercross and Motocross Championship series as a rookie in the same year, and again in 2012 with the Yoshimura-backed GEICO Honda team winning both 250 Supercross Lites titles. The RS-4 features a Polyresonant duplex chamber, a two-staged stepped baffle and an innovative carbon cone end cap.

  • 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
