Nah.

You only need a length of black pipe, some other fittings,
and maybe even a nice large general purpose off the shelf
heavy equipment muffler, and wham! Quiet.

You can use a random muffler from a junk yard if you are
feeling really cheap...

Look at how the thing is constructed. Can the mountings stand extra weight?
You may have to go the flex tubing route. A friend of mine tried a bigger
muffler and ripped the bolts out of the head and had all sorts of fun
fixing it. 8o(

Hey!

This is a metalworking group, one can assume that you'd know to add some
appropriate support, as required.

Many years ago I did a composite of the hole in ground trick, AND the pipe
w/muffler trick to quiet the generators at an underground/impromptu
rock concert out in a field.

I found a whole lot of 20 ft lengths of pipe under a bungalo, put bales of hay
in a 4ft high ring around the generators (sufficiently wide placement - like
6ft plus clearances) - ran the pipe from the exhaust outlet through a hole
cleared in the hay bales, then attached the stock mufflers at the end of the
20 ft pipe... quite much quieter, thank you...

From what I remember, the concert was fun... and the gens had no
problem...

:- )

I don't want to admit how many years back that was... geez.
