I recently bought my first monster, a 2016 R. It’s an amazing bike. Just came back from a 2000 mile European tour on it. It did everything brilliantly. I’ve got termi’s on mine and with the baffles out it just sounds stunning. Would recommend getting some if you don’t already have them.
Remove one hex bolt located at the end of the can on the side facing the wheel. Baffle then slides out.
Mine is missing so I can only assume they were removed at install. I will check the box with original parts in and see if they are in there.
