Also where’s a good place to source these?

No reason to over-think this. I simply went to my local hardware store, bought a dozen M8 ( ... I think, thread size from memory) plain old carbon steel long full thread bolts, and Dremel'd their heads off so to give me full threaded studs.

I then used SS nuts with high temp anti-seize on the threads.

Simple.

Looks good. Reason why I wanted to ask is that some forums had a big debate on studs vs factory so was curious. I have studs with copper nuts on my M3 and they’ve been great.

I do like that option as well if I can’t find the double end exhaust studs to just go with full threaded and cut the heads and retap the end. Will see what I can find tomorrow.

Thanks for the reply and suggestion
