I have a small Coleman powermate 4000W generator with a DIESEL (sic) engine.
Needless to say, it is quite loud, perhaps partly due to being a diesel.
Besides other things like building an enclosure for it, I heard that one could attach a car muffler to the exhaust instead of factory muffler. If that is so, can someone suggest where I can buy or how I can build the adaptor between the exhaust and a car muffler. Also, where can I buy a used muffler. The exhaust's opening is a rectangular protrusion about 1.2x3 inches.
