Yoshimura RS-4 full system

Rating: Not Rated Yet
Manufacturer: Manufacturer


The RS-4 muffler was developed in conjunction with the Yoshimura Suzuki race team with one purpose in mind... winning championships! That goal was accomplished during the 2010 AMA Supercross and Motocross season, as Ryan Dungey and his Yoshimura powered machine took the motocross world by storm as the first rookie in the history of the sport to dominate both series.

This Full System comes with a stainless steel header and mid-pipe, aluminum muffler sleeve, installation hardware, and detailed instructions to get you moving! Stainless Systems come with a USFS approved Spark Arrested insert installed in the muffler.
*all MX Model 150cc-450cc
