M4 Performance Exhaust Q7 Stage1 dB silencer quiet insert for M4 RM1 style mufflers

I had bought my 2018 MT-07 used and it came with the m4 exhaust with out the insert so while in the hyw the droning just killed your ears. But now with this insert it's has refined the sound to a comfortable level

Straight pipe is nice and all, and the system sounds amazing, but buy this to at least tone it down a bit. If not noise, get it to create at least some flow resistance.
