Appallingly Loud Onan 2800 Generator

I ordered a resonator and a downpipe to see if I could quiet the noise a bit.
Without anything running inside, except the fridge I get this at about 10 feet:

Without resonator, but with down pipe:

Generator shut off, quiet shop:

The tone is much more pleasant with the resonator. The down pipe also mods the tone, but not that much.
