Making my onboard generator quieter
Here's a good project that reduced the sound output on my onboard generator. Part number is of the resonator is 155-2449. I had a local car exhaust shop do the welding. Resonator sound comparison

So the Inverter model, despite running slower and having a completely different motor, has, under load, that same chugging or Poot-poot sound that my non inverter model has, and that resonator seems to have about the same effect on your inverter model as on my older non-inverter model.
I took my pipe to a one man muffler shop and he welded up some cracks in the 90 degree bend of the pipe caused by a broken hangar in the past, and he cut out a section and welded in the resonator.
I had bought the resonator to install on my 3600LP generator in a motorhome I had, but everyone who had tried it said it simply didn't have any noticeable change in sound so I never bothered to install it. After I got my trailer and realized the sound the smaller 2500LP made I tried it and that is what you see in my short video. That led me to install it and in that process I discovered cracks in the pipe at the 90 coming out of the motor from a broken hangar that had been repaired using inner tube or similar rubber that left a lot to be desired. As I also had the proper Cummins hanger, new, I bought with the resonator, I changed it out and fixed everything.
