Generator Exhaust

[DUNEDEMON]

Here's the deal, I've got a 6500 watt Generac Generator with a 10 HP Honda OHV engine. I use it when I go to the dunes to power my toy-haulers electrical stuff. The problem is that the fucker is too loud, I now have a little free time and thought I would look into building a new QUIET exhaust system for it. I don't know shit about small engines so I'm looking for advise and possible sources for a muffler, something small, the generator itself is portable and enclosed in a "cage" of sorts and I would like to keep the new exhaust contained within the cage structure. Any ideas?

I just got through doing the same thing to my gererator All I did was go to the local muffler shop look around till I found a muffler that would fit and welded a adapter to the existing nipple on the exaust manifold and then welded the muffler to that.......sounds simple if you say it fast, good luck

Wonder if you could take some silencer packing & pack it around the muffler & then bolt on some tin or something to hold it on. Would look like Jerry's Kids put it together, but who cares?hehe

LOL@ Jerry's Kids....

 

I would do the looking around for small mufflers. You might be able to gang up on them if they are small enough, i.e. weld 2 in a row or something. If I had my tubing bender I could bend you up a custom sweeping chopper style pipe...lol...

the have small mufflers at hardware stores like Lowes and Ho depot. They look like small canteens

We did that to our old big red for hunting, worked a charm made that sucker wisper quiet

Thanks for the ideas guys, unfortunately I've already looked at 6 different local shops and the smallest mufflers they have are WAY to big. The mufflers at the hardware stores that look like canteens are basically the same thing I have now. The pipe work is not that big a concern it will be easy. I was just hoping that someone else had gone through the same thing. I want the thing quiet, but I don't want to add so much backpressure to the engine that it starts running hot. Do you think a stock Banshee silencer would work? What about a T-5 silencer? Again this is a 10HP Honda OHV generator engine - think of it as a big block for your lawn mower.

That's a damn good idea, may pull out all the packing so there's not soo much backpressure like you were saying though. T-5...I dunno, would sound like a fuckin pissed off bumble bee probably.

Hell yeah man, thanks. I was going to post the same question because mine is driving me crazy!!!!!!!!!

[DUNEDEMON]

Well I'll try a stock Banshee silencer, maybee Got1 will to, anyone have any stock silencers they want to get rid of? Might be good for my generator - installing Yamaha parts on a Honda.

I'v seen an exhaust advertised on the ATV shows, called the stealth for ATV;s, I have wondered how it would work on a generator exhaust. Supposed to quiet an ATV quite a bit.

[DUNEDEMON]

philshee Thanks for the tip, I'll look into that.

[got1banshee]

As a matter of a fact I do have stock exhaust and I will try that!!!!

[DUNEDEMON]

Have you got the other half? are you willing to part with it?

[lincster]

That is way cool you are doing something. I hate it when someone pulls up next to us at the dunes and unloads a portable generator. Then they run the damn thing all night. TOO LOUD!!!! I can run my genny in my Warrior all night and you can't hear it.

Whatever pipe and muffler you can add on will help.

Try camping world, I bet they have something.

Heck, go to Onans website and see if you can buy a muffler all by itself.
