GP5500 Needs Silencer

Does anyone have a solution to the extremely loud exhaust on my Generac GP5500?

You might quieten the exhaust a bit by adding an extension to the muffler but there is still mechanical noise from the engine. Use a longer extension cord lol

Saw a utube video all the guy did was take piece of plywood and stack them on the sides with about a foot clearance on the bottom and it cut 10 dba off the sound and it still had plenty of air.

Yes indeed, changing mufflers is a waste of $. Lots of folks are building little enclosures to run them in which is fine as long as it has plenty ventilation. I reflect the sound off mine using a couple pieces of osb board deflecting it toward the woods.
