Product Description


Yoshimura R-77 Street Slip-On Exhaust with Catalytic Convertor

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 a single R-77 muffler along with all the necessary hardware and clear instruction for simple installation.
