Advice finetuning generator exhaust noise
I own a Onan Microquiet 4000 which I am extremely happy with. I have it roof mounted in a custom soundproof enclosure and for a generator it's size, I'm pretty sure this is the quietest unit I've ever...

back pressure will damage the engine. being on the roof there is nothing to block the sound from travling in all directions . at least when it is on the ground or in a compartment the sound will travel but not everywhere. Why is your gen on your roof? You dont say the roof of what?
