Yoshimura RS-4D Pro-Series Full System Exhaust
  • The RS-4D not only increases power and is light weight, but it also has a lower centralized mass coefficient to provide better handling.
  • The 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 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.
  • This full system comes with a titanium header and mid-pipe, carbon fiber muffler sleeve, carbon fiber dual-outlet end cap, installation hardware, and detailed instructions to get you moving.
  • Titanium Systems come with an AMA Pro Racing sound insert installed in the muffler.
