• R-77D muffler is a new design developed throughout years of racing efforts and hours of meticulous research and development by Yoshimura engineers
• Distinctive dual-outlet end cap design puts an enticing twist on the style of the original R-77
• Design also further increases the mufflers open outlet area, resulting in increased exhaust flow while maintaining moderate decibel levels
• Straight baffle for improved air flow

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.
