Yoshimura R-77 Exhaust Systems

Every element of the Yoshimura Full Exhaust System is designed with one thing in mind…Power!
The R-77 consists of a trapezoidal-shaped sleeve, maximizing muffler volume, while offering a sharp silhouette to compliment the bike's styling. The innovative Carbon Fiber end-cap is reminiscent of the R-55, featuring sharp edges for an attractive, eye catching appeal.

Featuring Yoshimura's innovative duplex headers, these headers offer superior mid-range performance with smooth torque and power curves for optimal gains. Yoshimura’s Full-System exhaust kits include a 4-2-1 header design with a single muffler mounted on the right side, minimizing unwanted weight for the performance oriented rider. The full system weighs in at only 13lbs.

**Note: 2009 YZF R1 is a 3/4 system with dual mufflers
