Ok, the exhaust is on! Now, this thing is loud

- Micron rate it at 106dB at 7k rpm! While I quite like the sound, I would like to air on the side of caution and fit a removable baffle. Especially since the legal limit in Oz is 94dB
I have found this:

& this

Now, my can has a 50.8mm outlet which makes me think the first option is the best, but the second is about half the price.
So - does anyone here use one of these generic baffles? and are they all just one size? I'd rather not get something too small that will rattle about.
Thanks for any insight
