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. That same R and D has been directed to developing the current generation RS-4, a unique design that provides an unrivaled combination of power and a quiet exhaust note. The RS-4 features a Polyresonant duplex chamber, a two staged stepped baffle and an innovative carbon cone end cap.

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