I have the 2005 version of the Generac Wheelhouse 5500 and have been looking for ideas to fabricate some type of muffler extension or even a replacement muffler that would quieten the generator down considerably more than it is today.
Any thoughts appreciated.
Your Generac Wheelhouse 5500 open frame generator is totally unsuitable for use in any organized campground and no amount of modification is going to make it so. Your best solution is to replace it with a significantly quieter inverter style genset, sizes of which range from ~ 1000 to ~ 7000 watts.
What he said ^^^^^^
Even if you find a way to make it significantly quieter, which may or may not be possible, it will still be too loud for use anywhere near other people. Your non inverter genny has to run at 3600 RPM, full time, in order to produce 60Hz power. The inverter type is designed from the ground up to be quiet and efficient, and varies it's RPM according to load, yielding lower sound levels and saving fuel.
An add on muffler won't come close.
