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.

  • Dual trapezoidal shape R-77 mufflers
  • Large volume of packing material
  • 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

Questions & Answers

  • What is the lightest muffler, carbon fiber or titanium yoshi R77 on 2014 Hayabusa? And are they sold in pairs?

    By: Doug

    These Hayabusa mufflers from Yoshimura are indeed sold in pairs.

    If you're after the lightest muffler possible, choose one with a carbon fiber sleeve as those are lighter than the stainless steel or titanium sleeve options available for the Yoshimura Hayabusa exhaust.
