generator exhuast silencer?

[txslowpoke]

Has anyone tried adapting a ATV exhaust slincer kit to a generator? I am talking about the cheaper big box store genny's.Maybe I am just hardheaded and have to try it to be proved wrong. I just cant see where that exhuast setup cant be adapted with good results. What say you?

Never tried, but have always throught the same thing, there's got to be something that can be done to quiet that thing down.

Most engine manufacturers now sell after market quiet mufflers that just bolt on in place of the original.
Try Small Engine Warehouse--Engine - Generator - Pressure Washer they may have something.

What really worked for me once---

I ran a length of pipe from muffler to an existing 'hole in the ground'
(maybe 2 ft deep X 2 ft wide) and had the pipe outlet near the bottom.

The raw earth sides of the hole deadened the exhaust so effectivly that I could hear the valves clacking away!

I'd like to do that to my riding mower. There is no reason it should sound like a Harley.

The problem with box store contractor generators is the RPM they run at. Most run at 5000-6000 rpm. 1/2 the noise you are getting is from the engine noise and not exhaust.

More expensive and quieter generators run at 3600RPM.

You might try one of these. The Quiet Spark Arrestor Muffler
They are kinda pricey, but Supertrap makes a great muffler.

I've seen/heard the ones on ATV's, they sure work. I think the deer can still here the atv comming.

I bought a small oval car muffler and and adapted it to the exhaust of the 8 HP B&S on my generator. It took away most of the exhaust noise, but as others have noted, a lot of the noise is radiated from the engine itself.

Have to agee with Tom, with the engines used on these genset, much of the noise is mech noise and a muffler won't do anything for a good portion of the noise being produced.

I disagree with Chris on engine speed. Direct drive models have to either run at 3600 or 1800 rpm to produce 60Hz power. You're going to have to spend >$2k before you get into units with 4-pole genhead that operate at 1800 rpm.

I put a small car muffler on my Generac, and found out that the engine and generator, were as mentioned by others, more of the problem. So, I put it in the barn and and close the door most of the way when I run it. You can still hear it at my neighbor's house 200 ft. away. Sorry, neighbor!
I once was on a movie set and they had a HUGE generator running that was almost silent! I have a long way to go!
