Product Details

Introducing Signature Series by Yoshimura - an offering of exhaust systems that a dealer can install with confidence. Our Signature Series lineup is the answer for today's dealer who is faced with a challenging marketplace. The applications for the Signature Series line cover the entire powersports spectrum, including many of our off-road applications. Everyone of our Championship Winning Motocross exhaust systems and nearly all of out ATV/Side-by-Side applications are all members of the Signature Series Family. All Signature Series components are tested, documented, and marked as required by federal and state regulations.


The 2020 Yamaha YZ450F has undergone significant changes in both motor and chassis refinements, and seems to be the 450 that many are choosing.


It's no secret that the Yamaha YZ450F has a very good stock system that many of our competitors can't beat. We spent a lot of R&D time in the dyno room and track to create our RS-4 Signature Series to what we think is the best aftermarket exhaust for the new YZ.


  • Pentagonal-shaped sleeve
  • Front muffler cap functions as a poly-resonant chamber which helps reduce noise
  • Two-stage stepped baffle
