Yoshimura RS-4 Race Slip-On Exhaust Honda CRF250L

The work that went into developing the Yoshimura RS-4 Exhaust design paid big dividends in 2010 with winning the AMA 450 Supercross and Motocross Championship series, and again in 2012 winning both 250 Supercross Lites titles. That same R&D has been directed to developing the RS-4 for Road Racing — a unique design that provides an unrivaled combination of power and a quiet exhaust note. The RS-4 Exhaust 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
  • Two-stage stepped baffle
  • Carbon fiber end-cap
  • Stainless steel mid-pipe (applicable models)
  • Made in the USA
