Onan 2800 sound is noticeable quieter.
Got the resonate for my B van with the 2800i Onan. Being in camp grounds prior, we can hear the echo across the campsite. I wanted something to tone the noise down. This has done that. Very pleased with the end result. Price was well worth the quieter tone.

Muffler to help quite generator
Compact muffler. Does quite generator but not as much as I would like. Have to get your own brackets.

It helps some
I got this for my Onan 2500 LP generator. It helped with the tinny sound of the exhaust, but the genset is just loud. Install was ok, not like others I’ve seen. There’s just slipped on over the pipe and they clamped it on. Seems like my exhaust was almost the same diameter. Had to make relief cuts in my exhaust to slide this on and then clamp it. I may just get a butt clamp, recut the exhaust pipe an inch shorter and install again. It does the job of changing the tone of exhaust, but don’t expect the Onan genset to magically become quiet like a Honda genny.

It helps!
The product performed as advertised. It didn’t bring the decibels down considerably but, the higher pitch/tinny sound produced by my Onan propane generator was muted quite a bit. I would say it “took the edge off” with regard to sound dampening.

Not effective
Cummins 2800W generator application; took multiple measurements of decibel output with stock exhaust (~102); took multiple measurements of decibel output with resonator (~103). The resonator did eliminate the pulsating sound rhythm of the exhaust and resulted in a consistent tone (no pulsating rhythm).

Works.
It helps. The sound is OK, not drastically quieter but it is quieter. The note of the sound changes quite a bit for the better, this gets rid of annoying buzz quality that the stock pipe has. Volume and irritation factor is reasonably improved, especially a short distance from the vehicle. Does this make it quiet? No. But for the price it does improve the situation quite a bit. I had it welded into the pipe by a local muffler shop.

Measured 1-2 dB LOUDER
I took readings from 5 places around the RV with a constant ambient background of 30 dB. This was actually louder, which could make sense because it had a much deeper bass sound that probably traveled farther. What a waste of money
