Neighbors will be happier if your run the exhaust into a galvanized
bucket filled with water. The exhaust, via suitable hose (few are) or
flexible metal tubing. should extend BELOW the water level. There
should be a top on the bucket, vented around the edges to direct the
much reduced noise DOWN.

I'll bet the water muffler does well at reducing the exhaust note, (at the
expense of considerable back pressure) but you will be surprised at how much
noise those Home Depot class generators make that is NOT from the exhaust.
About the only thing that will quiet them down is a heavy, remotely sited,
generator shed.

If you really want quiet, those inverter generators made by Yamaha and
Honda are awesome. Expensive, but after all this is an aviation group. Money
is obviously no object, right?
