I don't own a Champion generator, so I can't accurately rate the noise it produces while loaded. This is also true of other inexpensive generators, many of which have had similar complaints against them for noise.

What I don't understand is this; if the inexpensive generators save a lot of money on their purchase, seem to work reasonably well and are appreciated by their owners, why aren't they fitted with an aftermarket quiet muffler? If this is the only source of complaint, why not swap out the muffler for one of hundreds of aftermarket products that will quell the racket? Any parts store has a wide array of products, every lawn and garden manufacturer has a variety of quiet mufflers. It only takes a minimal amount of work, to adapt a different muffler to a threaded piece of pipe.

My neighbour has a Toro lawn tractor that sounded like a Mack truck. He bought and installed a JD compact diesel muffler, that was an almost exact fit size wise, The reduction in noise was remarkable, and there was no difference in performance.

If these generators are such a value, spending a little more to make them quiet won't break your budget. You will enjoy them more, and your neighbours will as well.

This one knocks the noise way down, we had one on an old Bobcat skid steer with a VH4D, V4 Wisconson. Don't need alot of noise or sparks while cleaning a poultry house.

Those mufflers look like an excellent application. Not only do they reduce the noise, but offer a spark reduction, which is always weclomed when ever these generators are used around straw, hay, dust etc.

For about ~$75 you can upgrade your generator to a safe and quieter unit.
