The flange is not installed as of yet but the quality of it feels very good.

The flange I received seems to be good quality. well made but it is useless to me as the threads are NOT standard 1" NPT and I can not find a threaded coupling that will fit the flange. The holes in the flange are on 2 in center and the flange does fit my Westinghouse 12,500 generator but it is useless as I can not use a coupling to extend the exhaust out of my shed. Buyer beware.

Well built but not NPT threads.Just go over to the electrical section of your hardware store and grab a 1-in threadedconduit coupler.It will thread onto the fitting and also thread on to NPT pipe.Also had to grab some M5-0.8 x20 to catch any threads in my Westinghouse 9500 TFC generator

I had to modify to fit my engine but it's on, the quality of steel used is very good and the welds appear to be of good quality as well.

I threaded on my muffler got about a half a thread on and when I tightened it it just mangled the threads and caused the pipe to dimple in because this is larger than 1 inch and not standard pipe thread. I figured it would be OK so I put it on my motor, started it and the gasket blew apart. 100% junk all the way around!!!

The bolts on the generator are a bit smaller than the extension nuts included. However this is adaptable to smaller bolts on a similar generator.

So when trying to install it it hit the heat fins on the engine. I ground a bit off the side and it slipped over the bolts and seemed as if it would bolt up but nope... when you try to put the nuts on they hit the pipe and can not be tightened.

I like that it was a perfect fit for my Westinghouse generator's exhaust.
