I have never pulled an exhaust stud before while doing pipes. This evening I’m 4 for 4. These copper flanged nuts locked on the studs and there was 100% no getting them off without the studs coming with them.

Going back to using just regular nuts with 12mm flats. So much for trying to get the “right” part.

Edit to add details:

The nuts in question are commonly available and sold as exhaust nuts. I got mine from Auto Atlanta - but many places sell them. The have a copper color to them and the bore is slightly oval. The are designed to lock on to the stud - which I did not know at the time. They go on tight and you can not remove them without pulling the stud.

There are flanged nuts that work fine.

Kinda furious with myself right now.

Continuing to live life as an object lesson for others…
