Yoshimura RS-4 Street Series Slip-On Exhaust


Yoshimura's Street Series exhausts do not require tampering with your vehicle's emissions control system while still delivering that special spirit the world has come to expect from a Yoshimura exhaust.

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
