You are fighting a loosing battle. A lot of the noise comes from the
intake and a lot just from the engine block. I've seen people go to
great trouble to mount auto mufflers to various equipment and it does
not make much difference. If it absolutely must be quieter, look for a
replacement Honda or Kawasaki engine. They are far quieter engines.

Did you install it right?
Did you get all the old gasket off and put on a new one?
Did you tighten the bolts/nuts properly?

Do you know exactly from where the sound is coming?
Set it at idle and listen and FEEL around for the exhaust leak
-- feel around before the engine warms up or feel for the puff
of exhaust gases.

If the noise is that loud and not coming from the
exhaust system, don't worry it. The engine will destroy itself
within minutes anyway.

I have the same problem. Replacing the "flame arrester" (it's not a
muffler) didn't help.

I don't know if this would work with your application, but I've seen
generators with metal 3/4" or 1" waterpipe (this assumes the exaust
hole in the block is threaded) exaust; a nipple then a T with 2
mufflers screwed into it. Quieted them down quite a bit.
