Yoshimura RS-4 Enduro Full Exhaust System

All Yoshimura Enduro Series exhaust components are equipped with USFS-approved spark arrestor, have forest-friendly noise levels, and are tailpipe emissions compliant.

The work that went into developing the RS-4 muffler design paid big dividends during development in AMA Pro Racing. That research was directed at developing the RS-4's unique design that provides an unrivaled combination of power and a quiet exhaust note. The RS-4 muffler features a polyresonant duplex chamber, a two-staged stepped baffle and an innovative carbon cone end cap.

  • Two-stage stepped baffle
  • Carbon fiber end-cap
  • Stainless steel header and tail-pipe improves flow over the stock exhaust
