Yoshimura RS-4 Slip-On Exhaust KTM 250 / 350 / 450 / 500

The Yoshimura RS-4 Slip-On exhaust has been put to the test and has proven its capabilities at the highest level of competition. In 2010 the RS-4 muffler helped Ryan Dungey claim the AMA 450 Supercross and Motocross championships in his rookie season. The Yoshimura-backed GEICO Honda team also took home both East and West Coast Supercross Lites titles in 2012 using the Yoshimura RS-4 exhaust.

Utilizing the same R&D that helped bring success at the national level has resulted in a unique exhaust design that provides an unrivaled combination of power and quiet exhaust note. The Yoshimura RS-4 Pipe features an innovative carbon cone end cap, a two staged stepped baffle, and a polyresonant duplex chamber which acts as a muffler within a muffler to help save weight and centralize mass.

Nearly all Yoshimura exhaust systems that have won Motocross or Supercross championships are members of the Yoshimura Signature Series. All Signature Series pipes have been tested, documented and marked as required by federal and state regulations.

Features:

  • Pentagonal-shaped sleeve
  • Polyresonant front muffler chamber which helps reduce noise
  • Two-stage stepped baffle
  • Carbon fiber end-cap
  • CARB/EPA tailpipe emissions compliant
  • Yoshimura Enduro Series muffler for Enduro models
  • Yoshimura Signature Series muffler for MX models
  • 100% Made in the USA
