That is a Nelson muffler. Onan number 155-2669. They would be the ones to call. Most likely cheaper than Onan

My mistake on the number. That is for a kit for a center mount muffler. Nelson should be able to tell you what one you need. I can send you another info sheet if you need it. Center mount is what you need.

Here's how to get a Nelson mufler:

Pick what you want from the catalog http://www.nelsonglobalproducts.com/catalogs/

Plug the part number into ebay and or google to see if it comes up with a seller.

Or call Nelson to find a distributor in your area.

What is wrong with the one pictured? Be prepared to pay dearly, even through Nelson. That one pictures looks like the critical quiet ones. $$$$$$$$

Why not look into the Maxim mufflers?

Maxims are excellent but spendy.
I had a nice one about 8" diameter and 3 feet long. I put it on my gen temporarily and yes it was quiet. But as it was all thinwall material it had a tinny pingy sound. As it was too big I didn't use it. If you want a Maxim I suggest getting one with thicker material to damp out the high frequency noise.

Re the comment: thinwall material it had a tinny pingy sound---". I have been using a Maxim muffler on my JB now going on some 46 + years. I never heard of such a complaint. Besides my Maxim is located very close to the JB and surely the operating sound of the JB drowns out any ? pingy sound. The purpose of the muffler is to attenuate the "exhaust" sound emanating out the tail pipe. Furthermore, ideally the muffler should be protected from the elements or its life will be severally shorted analogous to automobile mufflers. Just my opinion.

You know, Leon, it is possible that Maxim might have changed a few things in the last half century...

Jim yes, I suspect that is true. I am only trying to relate my experiences and investigation into a good JB muffler that met my requirements. Yes, it has been many years ago, that I studied this area because I wanted a relatively quiet sounding muffler and one that would allow my JB to breath without impacting its operation. I am very pleased with how this aspect turned out. There are a few factors which I felt were important and Maxim addressed my concerns. That is all I can say.

Default Re: Where to buy a muffler?

This thread has my curiosity up. I do not know but need to ask, is there a difference between a generator muffler and a car or truck muffler? I understand that the engine speed will play a part in how restrictive it can be. I would think that a 4 cylinder car muffler that works on a higher displacement engine that has a higher rpm would be no problem on a lower rpm smaller displacement engine.
What I don't know is if the baffel design would be the same.
Any ideas or experience?

They make several grades. This one despite it's size only weighed maybe 15 pounds. Very thin shell that you can deflect with a thumb push against it.

Yes say what? "Very thin shell that you can deflect with a thumb push against it." That's not my Maxim! Sure you can build your own, why you can merely bury a can in the ground. However, for me I like the technical information Maxim supplied and I am confident I have a good match for my JB and it sounds so mellow, the sign of a powerful machine.

Talking Re: Where to buy a muffler?

If you hate your neighbor then a muffler is optional . My sausage mufflers on my 4.0 BFA are so offensive I hate myself for installing them .
