The Yoshimura RS-4 slip on exhaust is a unique design with predicated power and a quiet earthy exhaust note that speaks volumes for performance. This RS-4 features all the benefits of our original RS-4 muffler, but with a unique turned-out end-cap, designed to direct exhaust heat and gases away from the bike's components. To top-it-off, we embossed our Yoshimura's 347 logo in the carbon for a clean look. With all its benefits in mind, the RS-4 is an obvious choice for your bike.

The RS-4 is pentagonal shaped muffler that features a carbon fiber cone end cap, two staged stepped baffle and striking good looks. The RS-4 muffler features a new front cap design that functions as a polyresonant chamber. This design makes for a quieter muffler with improved mid to top end power.

RS-4 slip on exhaust includes an RS-4 muffler, USFS approved spark arrester, all installation hardware, and step-by-step instructions.

Features:

  • 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
