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.
