I don't want to really complain about the noise, but I would like to quiet the generator down. This is for consideration mostly (as we have a pretty old generator and maybe it would be better just to replace it). After a short research, I noticed that some suggest changing the muffler. So here are some questions about it: 1: What type of muffler to use and where to get it from? 2: How was it fastened back onto the generator? 3: How much quieter did it make the generator (with replacing the muffler alone)? 4: Aside from the muffler, what is the main source of noise from on the generator? 5: What is the skill level (and which skills) the user will have to have to complete this task? Answers needed to help me get a little more understanding on the process and also what others have already done. Since, well, I should have shopped around and bought a quiet one in the first place. Still I would like to - if it's possible - to reduce the noise. If that's not possible (or way too complicated), then opinions needed on quieter models, gladly there are plenty of options. Our current gen is Champion C46540 (3500 Watt). Also I was thinking about getting two Honda EU2200i units even, for better portability. So if it'd be more effective than any of mods, then I might go with this option.
