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. Preliminary 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 tail-pipe, titanium muffler sleeve, installation hardware, and detailed
instructions to get you moving! Titanium Systems come with a AMA Pro Racing sound insert installed in the muffler.
