For those of you who replaced your rusty exhaust flange studs...

Are you saying a nut like this in the pic below?



If so then how do you screw a splined stud into that? This is the 6 splined studs that I took out of mine and there was no evidence of any captive nut on the header flange?



These had to be pressed out with a vice after a lot of heat.




As I said in my first post mine is a Euro S and the US has a different exhaust layout so maybe it’s different but I know what I took apart.

Yes, similar to that. It's been a while since I had mine off, but I believe two bolts on each side were splined studs and the third was a standard bolt with captive nut. A real PITA.

I replaced all of mine with SS bolts and nuts.
