M4 Full Exhaust R3
This Full System is Phenomenal , I got it for my 2017 R3 , and once you wrench out your stock system and put this one it’s amazing. I did it myself and it was pretty simple for the most part , a few harder and not detailed parts but overall 1-5 install 1 easy 5 hardest I’d say 2 , I’m still relatively a novice on working on my motorcycles and this was easy enough. Get it take the baffle out and you’ll be on your way to sounding really good and turning heads

Great deal
This is a great exhaust system. Mine came with a db killer and an O2 sensor bung for an 18mm and adapter to the stock O2 sensor. It sounds fantastic and fits very well. No need to remove fairings to install unless you replace the O2 sensor.

Why is there no info about this exhaust?
I'm curious on how this exhaust sounds and performs but there is no information about it. I didn't even know this exhaust had existed. May you make a video about it?
