Product Description


Yoshimura R-77 Race Series Single Slip-On Exhaust

If you're looking for that competitive edge, look no further than Yoshimura's Race Series exhausts. These exhaust components are designed with nothing but power in mind. Each Race Series system is developed in accordance with noise compliance regulations imposed by most race sanctioning bodies worldwide.

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.

This single-muffler design eliminates the original dual OEM muffler configuration for a significant weight savings. Each kit includes a single R-77 muffler and mid-pipe, along with all the necessary hardware and clear instruction for simple installation.

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

    As the muffler fits behind the exhaust valve on 2009-2011 Suzuki GSX-R1000 models, no - you will not need to remove or otherwise make any modifications to that part of the exhaust. It's a rather straight-forward installation that removes the removes the catalytic converter.
