Exhaust install, any ideas for dealing with the turbo side corroded nuts?

During my first installation of a 996TT exhaust, I broke the original studs when I tightened and torqued the nuts to spec. As a result, the stud was broken flush on the turbo side, which made removal very difficult. Since then, I have replaced all the studs on every exhaust swap.
But to each their own.

I cracked all 8 nuts so I never put any torque on the studs so they are all intact.
I wasnt aware they should be replaced when I started this but next step is replacement.

Typical process for this is you drill a slightly smaller hole in the stud remnant, and then use a tool called an easyout, which is reverse threaded...So as you turn it counterclockwise, it tightens and removes the broken bolt/stud. You would want to really soak it first with PB Blaster or similar penetrating oil.
If that fails, or seems ineffective, you may have to weld an extension to the stud and then back it out that way.

Can you explain the process you used to remove the nuts and studs?
Thanks

I ended up reusing the old studs, after cleaned up they looked just fine and install was very simple.
I am going to order new rear o2 sensors as well, the threads on them looks quite bad as well.
The Kline looks like this at moment, with bmw nuts

Silly question but what size are the nuts? I went through a similar problem when I removed my stock exhaust, ended up paying $800+ for a shop to finally get it off. I have new porsche studs and nuts on the car but I would like to switch to nuts that aren't going to weld themselves to the car. Getting a different exhaust pretty soon. Those copper nuts look like a good idea.
