Yoshimura RS-4 Race Series Slip-On Exhaust

If you're looking for that competitive edge, look no further than Yoshimura's Race Series exhausts. These exhaust components are designed with nothing but power in mind. Each Race Series system is developed in accordance with noise compliance regulations imposed by most race sanctioning bodies worldwide.

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.

  • Pentagonal-shaped sleeve
  • Front muffler cap functions as a polyresonant chamber to reduce noise
  • Two-stage stepped baffle
  • Carbon fiber end-cap
  • Includes all required hardware and installation instructions
  • USFS-approved spark arrestor
