M4 Performance Exhaust Q3 Stage 2 dB silencer for GP style mufflers

The muffler silencer worked as intended. You will need snap ring tools to get the ring into the muffler to hold the silencer in place, but other than that, it's great. It fit perfectly in my M4 exhaust and now I can finally hear myself think.

Bought the M4 muffler for my Kawasaki Eliminator. The Q1 baffle is rather loud. Ordered a Q3. A bit quieter, and a nice sound.

I was a bit skeptical this would be some cheap version but I was wrong. It works very well! My exhaust is definitely a bit quieter. Which was what I was looking for. This fit my M4 gp19 no problem.

For my ‘21 Zx6r It is worth it, get rid of the droning in low RPMS but still sounds nice and loud when you get the bike moving and are going through gears, little quieter overall but I would say just at the right volume Plus if you got Karen neighbors cold starts shouldn’t be as much as issue anymore. Give it a try for sure

The game change when you put an original part. M4 db killer works great. About 30% less of noise. Sounds perfect! 100 % recommended

The media could not be loaded. Got the bike used without any insert in the muffler (i.e. straightpiped), so cannot compare with the stock one. But sounds pretty solid and definitely much better than before.

This is the Sound I was looking for. Wait for break in period....

Dose not make much of a different. Need more lower tone at run speeds.
