Sound Insert Kit DB Killer for Yoshimura RS-2 Mini Mufflers (INS-25-K)

These sound inserts decrease the dB level of a Yoshimura RS-2 Mini full system by a few decibels. Will work with all Yoshimura RS-2 mini-systems (full Race system or slip-on Street system). If you're running an RS-9T system on your Z125 Pro (2017-2022) or Honda Grom (2014-2020), 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!
