Carolyn, I think that mikestock's stack is the best bet for you if you have the storage room. I made one for my Bounder years ago and spent somewhat more but I used 4" laminated drain pipe from Lowes and 1/8th X 3/4 strapping and an actual piece of automotive exhaust pipe that was expanded to fit the 4.5K Onan's exhaust pipe and bent into an ell.
I don't like running my 5.5K Onan in campgrounds and so I have a Chanpion 2K Inverter type that I use. I think I will look at it with the idea of adapting Mike's idea to the Champion. To further silence the Champion, I might extend the pipe 2 or 3 inches into the stack as Genturi has started doing. I thought the pipe needed to end below the bottom of the stack but it doesn't. I made an adapter for the one I made for the bounder extending it about 2" inside the stack and it did not heat the generator or the stack but it did reduce the noise at ground level, it carried up above the roof line along with the exhaust gas.
