Making my onboard generator quieter

My EU2200 rides in my cargo trailer. The noise it makes compared to the onboard gen is very close to the same.

And yes, the tone is much better with the resonator installed. It eliminates the "sputtering" sound from the exhaust.

There's no vacuum cleaner that cools an RV, nor is there a lawn mower powering anything.

underneath is not my idea of glamping. Been using a Honda 2000 forever and now have an LG 9500 dual inverter cooling my Roadtrek.

I would be interested in seing the difference it makes, if any inside the camper.

Sure seems to make the sound more acceptable.

Granted its only a video, while the meter may have determined the resonator made a difference. I could not hear much of a difference listening to the video.
I found the difference to be minimal at best. Not enough to make a difference or change my camping scenario

Nice upgrade, thanks for sharing.

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.

It's not deceiving at all. Watch the video and you can see that the resonator did indeed reduce the sound.

Agreed! CharlesinGA provided a great example of the improved sound. I would opt for that mod in a heartbeat.
