Also where’s a good place to source these?

Lots of people say stainless for exhaust but that is a mistake in my opinion.
Stainless is very hard if you brake one off ( and it does happen with stainless)they are hell to drill out.
So I use a soft material such as grade 4. Then If I have to drill it out it drills easy.

I have found common exhaust studs ( the type that are threaded on both ends) at Ace Hardware.
You will have to check to see if they are Metric so they fix the Porsche.
Napa auto parts. would be another source.

Brass nuts can be a little harder to find but Napa should be able to help.
