Product Description


Yoshimura R-77 Signature Series Dual Slip-On Exhaust

Yoshimura Signature Series exhaust components are the answer for riders faced with ever-tightening noise and emissions regulations at the federal level. All Signature Series components are independently tested, documented, and marked as required by state and federal regulations as CARB/EPA-compliant.

Yoshimura created the R-77 muffler to match the radical design of the modern motorcycle perfectly while at the same time reducing weight, adding power and giving your bike a distinctive deep exhaust tone. The R-77 muffler consists of a trapezoidal-shaped sleeve, maximizing muffler volume while offering a sharp silhouette to flow with the body. The innovative end cap is reminiscent of the Yoshimura R-55's design, featuring sharp edges for an attractive, eye catching appeal.

  • Straight baffle for ample flow
  • Innovative end-cap shrouds the terminus of the muffler for an unmistakable look
  • Stainless steel tail-pipe
  • Includes instructions and all required installation hardware
