One exhaust stud broke and another came out entirely as the nuts were seized and the studs were rusted. Does anyone have a recommendation for replacement exhaust studs? I was thinking of using full steel studs with copper or brass nuts.

I also had seized studs and nuts.  I was able to get the studs out, but the nuts are stuck to them.
Harpers had new studs.  Steins had the wrong parts. This was two years ago.
I could not find the nuts, nor something similar anywhere.  I gave up and used these instead:  https://www.mcmaster.com/94150A345/
They are not the same thickness and I added spring washers (https://www.mcmaster.com/92161A052/)  The washers seem weak and probably useless,
but it felt right to add them.
I re-torqued the nuts after a few heat cycles.  They had not moved.  I added a second nut as a lock.

I had to buy a pack of 50 nuts.  If you want to try them, send me a PM and I'll ship you some.

I have the same job to do at some point in the future. I'll probably use stainless steel coupling nuts and trim them to length in the lathe.

I haven't had the studs out yet, but McMaster-Carr likely has something that will work. These may not have the correct dimensions, just using it as an example.
