Product Details

    Yoshimura Off-Road RS-4 Signature Series Slip-On Exhaust

The Yoshimura RS-4 muffler for Off-road Racing has won multiple Supercross and Motocross titles since its inception. Yoshimura developed the RS-4 in the R&D lab called the Motocross track, 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.

  • Delivers huge power at a very light weight
  • Offers better handling thanks to a lower centralized mass coefficient
  • Uniquely-styled pentagonal muffler body with a carbon fiber cone end cap
  • Front cap design functions as a polyresonant chamber to lower dB output while improving mid- to top-end power
  • Two-staged, stepped baffle
  • Tapered headpipe delivers optimal flow and performance
  • Stainless systems come with 94 dB insert installed (meets AMA competition requirements), 2 meter Max insert in the box
