Went to take my motorhome out this past week from the storage place and the muffler off of my generator is gone. Either I bottomed out and knocked it off last time I took it out and didn't realize it or someone took it. Needless to say, it is extremely loud now. It is a Generac Primepact 55G on a 2001 Gulfstream Conquest and I can not find a replacement anywhere online. Anybody have any ideas as to where I can get one? Thanks.
