This Yoshimura R-77 Exhaust has been designed to offer peak performance for your sportbike without breaking the bank. As with most Yoshimura Exhaust Systems, you can expect that the R-77 was developed and tested on the race track and that means this motorcycle exhaust will provide some of the best in class performance available. The R-77 muffler has a very unique trapezoidal design that'll set you apart from the crowd while still providing the necessary increase in horsepower and torque you'd expect from installing a Yosh. "Just put a Yosh on it" rings true today as it did 10 years ago.
Please consider installing a motorcycle fuel controller, such as a Dynojet Power Commander, with the installation of an aftermarket exhaust system.
The popular R-77 offers outstanding performance, thanks to being developed in the heat of competition. It features a trapezoidal design, which allows a large volume of packing material and in turn delivers top performance with minimal sound increase. The R-77 muffler’s front cap is MIG-welded, while the end cap is riveted using high-end 304-L polished stainless steel rivets and bands.
