YOSHIMURA RS-4 MUFFLER YAMAHA YZ 450 F 2018-2022

YOSHIMURA RS-4 MUFFLER

Code: 234832D320

The 2020 Yamaha YZ450F has undergone significant changes in both engine and chassis refinement and appears to be the 450 that many go for.

It's no secret that the Yamaha YZ450F has a great stock system that many of our competitors can't beat.

We spent a lot of R&D time in the test room and track to create our RS-4 Signature Series for what we think is the best aftermarket exhaust for the new YZ.

Characteristics

The front muffler cap functions as a poly-resonant chamber which helps reduce noise

Two-stage stepped baffle

Carbon fiber case back

Exhaust terminal in stainless steel

Repack kits, optional inserts and spark arrestors are available for all models

Proudly made in the USA.
