Product details

Yoshimura KX250F 17-20 RS-4 Stainless Slip-On Exhaust, W/ Aluminum Muffler

The work that went into developing the RS-4 muffler has paid big dividends in Off-road Racing; winning multiple Supercross and Motocross titles since it's inception. We've developed the current generation RS-4 based on that research & development, and the result is a unique design that provides an unrivaled combination of power and quiet exhaust tone. The RS-4 features a Polyresonant duplex chamber and two-staged stepped baffle for increased performance, while a carbon cone end cap finishes off its innovative styling.

  • 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 tail-pipe
  • Repack Kits, optional Inserts and Spark Arresters are available for all models

Dashed steps show overdue periods with no completed crawl confirmation. Every line stops at that listing’s last confirmed check and is never extended to today. Prices are not live and may have changed since the last point shown.
