Yamaha YZ450F 2014-2017/2016-2017 FX/2016-2018 WR450F - Yoshimura Signature Series RS-4 Slip On

YM-234812D321 - Yoshimura Signature Series RS-4 slipon (stainless/aluminium/carbon fibre) for Yamaha 2014-2017 YZ450F, 2016-2017 FX and 2016-2018 WR450F

Signature Series RS-4 Slip-On Stainless/Al/Carbon Fibre:

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. We've 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.
