Product Description


Yoshimura R-77 Street Series Dual Slip-On Exhaust

Yoshimura's Street Series exhausts do not require tampering with your vehicle's emissions control system while still delivering that special spirit the world has come to expect from a Yoshimura exhaust.

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. Each kit includes dual R-77 mufflers along with all the necessary hardware and clear instruction for simple installation.

  • Dual trapezoidal shape R-77 mufflers
  • Maximized muffler volume
  • Innovative end-cap shrouds the terminus of the muffler for an unmistakable look
  • Removable low-volume exhaust insert

Questions & Answers

  • What needs done to the bike to take the inserts out for louder exhaust?

    Not much, really. Each insert is held in place with a single bolt that requires an Allen wrench to remove it. You'll need to pass the tool through the Yoshimura R-77 end cap to get to it. Fortunately, the muffler itself has a passageway molded into it specifically for this job. There's even a rubber plug on the end cap to keep road debris &etc. out of that port. It'll take you but two minutes to pull or install the sound insert.
