I put a Thrush muffler on a loud generator once.
Welded a flexible stainless nipple to the inlet side of the muffler and removed the stock, screw-in baby muffler and threaded the nipple into the head.
Had to make a tripod to hold the thing out away from the side of the Genny but it sure did make it quiet. I used that thing for several years like that.
I no longer have the genny but I believe that muffler is somewhere buried in the back shed.
