1. Definitely a must have

If you're anything like me and love your M4 exhaust but live in a condo/apartment complex this is certainly very helpful to have! I have a 2019 Kawi ZX6R with an M4 Street Slayer full system so my bike is a little on the loud side and I want to be respectful of my neighbors. Also, I live in California so enough said about riding a street bike with a full system haha. Now that I have this thing in I no longer need to pull my clutch in when I lane split next to a cop.
By the way, I got the Q6 stage 2 DB reducer for my Street Slayer. It fits perfectly and doesn't sacrifice a good sounding tone. It does make it noticeably quieter and helps out a lot. It's worth it.

Definitely glad I bought the dB for full exhaust still very loud but not too obnoxious

Got this because my bike came with an M4 exhaust with no baffle and it was just TOO loud, made riding unpleasant. Now I don't have to worry about annoying my neighbours and can ride in comfort. Highly suggest if you don't want a stupid loud bike but like the look / sound of the M4s

I bought the Q5 Stage 1 baffle to reduce the sound of my 2015 FZ-09 M4 exhaust system when I would leave for work early and when I would arrive home from a late ride. This is the perfect in-between for my needs as it fits the early/late departure/arrival without sacrificing the on-road noise that helps other drivers with motorcycle awareness.

This had exactly the right amount of sound reduction that I was looking for

I bought the Q4 stage 2 reducer for my 2017 FZ09 M4 exhaust. The stock M4 exhaust was just too loud for my taste and the neighbors. This reducer helped quite a bit. It's just loud enough to let other vehicles know you are there but not too loud anymore. Would definitely recommend.

The current item has not arrived perfectly, but it is correct that you have applied for the item in the picture.

This insert worked great. It removed much of the droning at highway speeds and has a deeper tuned sound. After running it hard all weekend, I personally believe the M4 exhaust should come with this silencer and have the louder one as an option.
