You would think someone would come up with a super muffler just for
that purpose. Even if it's as big as the generator, as long as you
could put it next to it and connect it and it made it much quieter
you'd think a lot of people would want it and pay a decent price
for it. A $1000 generator and $300 muffler sounds like a good option
compared to a $3000 quiet inverter generator.




Lots of times the generators make mecahncal noise and an exhaust muffler
would not be much quieter.

I'll bet 90% of the noise and almost all the objectionable noise is
from the exhaust.
