Yoshimura RS-4 Exhaust System Husqvarna / KTM / Gas Gas 250cc-350cc

The work that went into developing the Yoshimura RS-4 Exhaust System 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&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.

Features:

  • Pentagonal-shaped sleeve
  • Polyresonant front muffler chamber which helps reduce noise
  • Two-stage stepped baffle
  • Carbon fiber end-cap
  • Titanium Head pipe
  • CARB/EPA tailpipe emissions compliant
  • 100% Made in the USA
