Description
The 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 and Race results have shown that it offers increased horsepower and torque
throughout the power curve, especially in the bottom to mid RPM range.
