Yamaha Yz450f 2014-17 year models

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.

  • Pentagonal-shaped sleeve
  • Front muffler cap functions as a polyresonant chamber which helps reduce noise
  • Two-stage stepped baffle
  • Carbon fiber end-cap
  • Stainless steel header and tail-pipe
  • Repack Kits, optional Inserts are available for all models

Note: Installation of a new exhaust system may change your motorcycles fuel-air mixture requirements. Please consult the manufacturer directly with questions regarding any modifications that may need to be made during, or after installing their product. If a jet kit or EFI controller is recommended please see the Intake/Fuel section for products available

Note: Exhaust discoloration (bluing) is caused by engine conditions such as cam timing, fuel-air mixture, operating temperature, etc. It is not the result of defective manufacturing; therefore it is not covered by any warranty. See the Chems/Lubes section for products to help remove or prevent exhaust discoloration
