Please see photos to assess full condition. Getting the most out of an engine is what the engineers at Yoshimura R&D do best, and they’ve wasted no time in developing a new version of their race-proven RS-4 exhaust system to maximize performance.
By adding a Yoshimura RS-4 full system, riders will feel a significant boost in power and torque all the way from idle to redline.
The RS-4 is Yoshimura’s most advanced off-road exhaust system yet. The compact RS-4 muffler utilizes a duplex chamber design to maximize flow while offering excellent noise reduction.
The end result is a lightweight muffler that will lower sound emissions while increasing performance. RS-4 systems can be tuned to match whatever noise restrictions you might face through interchangeable sound inserts, which range from the USFS approved spark-arrested insert to the AMA pro racing legal insert.
