5.0 out of 5 stars Pretty quiet for its size
Reviewed in the United States on December 19, 2023
Verified Purchase
I was a little skeptical that this small muffler would quiet my generator as much as it did. Keep in mind that the generator is still pretty loud but not nearly as bad as it was without a muffler. The muffler fits 1 inch male pipe thread (NPT) and works well to reduce the noise to a level that I can now be around the generator while it is running.

Good sound, not loud, but has a good sound. Screwed right onto 1" threaded exhaust header. It turned from silver to a gold color within about 30 minutes of being subjected to the exhaust heat but I still like it.

4.0 out of 5 stars Good muffler
Reviewed in Canada on November 23, 2023
Verified Purchase
This muffler fits exactly how it is supposed to and looks to be a direct replacement for the factory version. With that being said the muffler has been shot for so long on my mower that I can't say whether this one works as good as the factory muffler or not. It is definitely much quieter than the mower with the rotted muffler but I can't say for sure that it works as well as the OEM version. If you are in need of a new muffler and this is the right size I wouldn't hesitate to get it. It dampens the sound and is a great price.
