Spark Arrester Kit DB Killer Insert for Yoshimura RS-9T Mufflers (SA-15-K)

Not only does this new spark arrester decrease the dB level of a Yoshimura RS-9T full system by a few decibels, but it also arrests the spark and enables you to travel off-road with your little primate. Will work with all Yoshimura RS-9T systems (full Race system or slip-on Street system). If you're running an RS-9T system on your TNT 135, 2022 Grom, or other bikes and would like to tone it down, this is what you'll need! It'll reduce noise by approximately 4 dB and it will also increase performance and torque due to better balance in backpressure!       Includes ONE Replacement USFS Approved Spark Arrester for RS-9 Off-Road Mufflers. Dual Muffler Systems require TWO Spark Arrester Kits.
