Installation was a breeze. Exhaust adapter fit perfectly on my Western House 9500/12500 DF generator. Noise level is considerably lower than before even though it is not a issue where I am located. Everything appears of good quality. Would recommend.

This did exactly what I was hoping, however when I went to shut the generator Down by shutting off the gas, the muffler popped loud and blew a flame about 8” out of it every time it popped, kinda scary

This is anything but universal! Unit looks good, but if you have a Duramax generator then this won't fit. The seller tried to help me with getting an adapter, but even that didn't help.I am changing the rating to give credit to the seller who has gotten back to me. When they didn't respond timely I thought that they had abandoned me. However, it wasn't intentional and they got back to me. Adding two more stars for the stellar customer service.

Used this extender to vent exhaust gases from my custom built shed. The parts are heavy duty. My generator required the round adapter. I removed the spark arrester from the muffler and did have to drill holes in the muffler cover, as none of the adapter holes lined up with the spark screen holes. That was no problem. I used muffler sealant to avoid leaks. The flex hose diameter was exactly the size to fit the adapter (1.5"), with no sloppiness. Again, I used muffler sealant at the joints and then tightened the included clamps. The wall plate was an easy install. However, the adapter fitting was only spot welded in three places, so it was necessary to use sealant around the fitting. I purchased this mainly for exhaust extension through the wall, not so much for noise abatement. And the price was reasonable compared to other similar products. There is no reason to not recommend this brand. It is described accurately, is top quality, and simple to install. All parts were packed with care in bubble wrap. I did not need to contact the seller.

The products all generally looked good, however some of the welds on the adapters were not that great & I will rework. Otherwise, parts were as advertised. Sad to say that we cannot something like this in the US & have to purchase from China

Comes with everything you need to make it happen. I was able to fit it inside of this little shed for it. Gets the exhaust out the back and away from the house. Everything was well built.

It extends the exhaust, but doesn’t reduce the noise. I am a bit disappointed.
