Yoshimura RS-2 Slip-On Exhaust Yamaha WR450F

The Yoshimura RS-2 Slip-On exhaust is a potent and versatile muffler that was engineered to provide useful power gains throughout the entire RPM range. The pyramidal shape of the canister offers increased durability and allows for greater packing volume which lowers sound levels.

All Yoshimura Enduro Series exhausts are tailpipe emissions compliant, provide forest-friendly noise levels, and come with a USFS-approved spark arrestor. Working in conjunction with factory race teams has allowed Yoshimura to increase performance, keep sound levels to a minimum and centralize mass. The end result is a sound compliant exhaust system that gives you an unparalleled competitive advantage.

  • Diamond-shaped sleeve
  • Stainless Steel header
  • Large core and increased muffler packing volume means quieter operation
  • CNC Machined mounting bracket
  • Yoshimura Enduro Series muffler
