Yoshimura has been the official exhaust supplier to several professional racing teams for years now. All of that racing experience has helped Yoshimura in making an exhaust that compliments an already great bike. The new Yoshimura RS-4D builds on the technology that has made the RS-4 a force to be reckoned with on the racetrack, enhancing its rock solid performance. By increasing the amount of open area at the exhaust outlet, the Yoshimura RS-4D Titanium Full System increases airflow, resulting in smoother power delivery and increased throttle control. Testing has shown it offers increased horsepower and torque throughout the power curve, especially in the bottom to mid RPM range where riders need it most.
RS-4D Titanium Full System comes with a Titanium header and mid-pipe, Titanium muffler sleeve, and Carbon Fiber Dual-Outlet End cap.
Includes installation hardware and detailed instructions to get you moving!
RS-4D Titanium Full Systems come with an AMA Pro Racing sound insert installed in the muffler.
