I want to quiet a loud portable 5KW generator?
I know about adding a larger muffler but I do not want to reduce the engines power by restricting the flow and that is only half the noise issue, the other half is the mechanical noise from the engine.. I have seen the sound deadening generator enclosures / shelters for them to run in but they coast 800 and up. I cannot find any plans to build one myself . Anyone know where I can find plans for one or have other suggestions?
