Yoshimura RS-4D Pro Full Exhaust System Titanium Fits Yamaha YZ250F 2007-2012

Product Details

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 mid-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.
