Yoshimura RS-4 Slip-On Exhaust System
*Exhaust ONLY. Bike Sold Separately*
The 2020 Yamaha YZ450F has undergone significant changes in both motor and chassis refinements, and seems to be the 450 that many are choosing.
The work that went into developing the RS-4 muffler has paid big dividends in Off-road Racing; winning multiple Supercross and Motocross titles since it's inception. Yoshimura developed the current generation RS-4 based on that research & development, 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.
Features:
- Pentagonal-shaped sleeve
- Front muffler cap functions as a polyresonant chamber which helps reduce noise
- Two-stage stepped baffle
- Carbon fiber end-cap
