Huge difference. About on par with a running engine now, instead of a full size air compressor. Which is what it is, just small and used in reverse.

It was loud enough to be embarrassing (not that anyone looked over, but still), and made me not want to turn her on in the wee hours of the morning lest I disturb the neighbors. Now it's a mellow thrumm.

The muffler by itself only made a minor difference. Putting a second piece of hose coming out of it made it really quiet. (Something to remember if using one of these as an engine muffler?)
