Description
Yoshimura has been the official exhaust supplier to Team Honda Racing for several years now. All of that experience has helped Yoshimura in making an exhaust that compliments an already great bike. The RS-4D not only increases power and is light weight, but it also has a lower centralized mass coefficient to provide better handling. Additionally, an overall improvement to the big Honda's power delivery was also realized.
The new RS-4D builds on the technology that has made the RS-4 a force to be reckoned with on the racetrack, enhancing it's rock solid performance. By increasing the amount of open area at the exhaust outlet, the RS-4D increases airflow, resulting in smoother power delivery and increased throttle control. Testing has shown that it offers increased horsepower and torque throughout the power curve, especially in the bottom to mid RPM range.
Titanium Systems come with an AMA Pro Racing sound insert installed in the muffler.
