I actually have Doug's cutouts, and I believe they are made in America, but who knows for sure anymore. The only issue I had was one of them died when it was nearly new. I called Pertronix/Doug's and had a replacement on the way immediately. They have great customer service and no complaints with them. Any body can produce a defective part. It's how they handle the issue that matters to me.

I spent a lot of time researching the various products on the market before I invested in these, and there are many complaints about the carburetor butterfly style not sealing well after they're used for a short time. Some sit flush in the bore, while others have a notch for the plates to shut against which I assume would work better (at least theoretically).

I also had my son whip up a pair of block off plates I carry in the truck, so if one of them ever fails in the open position, I can simply remove the electric portion and block off the pipe.

The electric cutouts are the most fun item I have ever owned on a motor vehicle, and we use them virtually every time we drive the truck. In Washington State they are only illegal on a public highway/street. This means they are legal on private property (like parking lots). In California any exhaust cutout is illegal period, in use or not.
