Yoshimura Street RS-4 Slip-on Exhaust System '09-'12 Kawasaki ZX6R

The work that went into developing the RS-4 muffler 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 current generation RS-4 for Road Racing — 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.

  • * Pentagonal shaped sleeve
  • * Front muffler cap functions as a polyresonant chamber which helps reduce noise
  • * Two-stage stepped baffle
  • * Carbon fiber end-cap
