Questions & Answers

For this, what is the clamp size? Is this compatible with my Onan 5500?

The inlet clamp will be 1 1/2 inches wide, and the outlet will be 1 1/4 inches wide. I hope this information is useful.

Onan 6 is what I have. The muffler part number is 155p1181, according to the parts catalog. Will this be sufficient in its place?

My grade is a 6. 5 also. This is the muffler I ordered, and it's fantastic. It's extremely quiet and much less expensive than the one recommended by the parts catalog. Because the inlet is larger than the original muffler, you'll need to use a smaller pipe.

Is this a straight out exhaust or a side exhaust?

This is what I put in my RV. From the front to the back, it was hooked up to my RV. To get it to exhaust out the side, I added a 90° pipe with a chrome tip.

How big are the inlet and outlet diameters?

Selected User Reviews For Cummins 1551258 Onan Muffler

A Generac NP52G RV generator was used for this installation
3/5

An adapter from 1 1/2 to 1 3/8 is needed. It's a lot quieter than the old, rusted muffler. The muffler body is a little longer. The total length is almost identical. Because the muffler's inlet is 1 1/2 inch, I had to go to a local muffler shop and get a reducing adapter. Metal that is very thin. The moisture drain plug could not be removed. I'm afraid I'll damage the muffler because I'm in such a tight spot. I saved money because it's only about $100 cheaper than the Generac muffler on Amazon. Because the galvanized finish on this muffler appears to be thin, I painted it with Utra High temp paint for gas grills.

It can be used on a variety of generators, not just Cummins
5/5

This is also applicable to a generator. I was unable to locate the generac model muffler and instead came across this one. The difference in length is about an inch, but it was fine with the right dimensions to bolt right up.

Does an excellent job and is simple to set up
5/5

While not as quiet as a Honda generator, it did a great job of quieting down my 2500 Onan RV generator. Now I don't have to be embarrassed when I crank it up for the occasional needs, and I can hear myself while inside the RV.

The fit is perfect
5/5

This was purchased to replace the rusted-out one I had previously purchased. The muffler on my Emerald Plus 6500 generator in my motorhome is worn out. It seemed to be a natural fit. If you know how to weld, it's a fairly simple process. Otherwise, you should buy the adapter because they will almost certainly be rusted together.

On my Generac generator, this is a fantastic upgrade

Excellent value for money
5/5

Although this was not the exact part number for my Onan generator, the size and appearance were ideal, and it literally saved me hundreds of dollars. This is a fantastic muffler at a fantastic price! Thank you very much!.

wrap it
5/5

metal that is very thin As this is the third one I've installed, I'd recommend using HIGH TEMP exhaust wrap to burn out any water as quickly as possible while in use. A larger "carbon plug" has been added to the bottom of the square, which should make it more difficult to twist off.
