Exhaust studs for secondary cats

[Essex-man]

Hi all,

Boring question but one I’ve been search for the answer for.

I have swapped my 2015 PFL RS3 secondary decats for Milltek and live the change...

I want the original secondary Cats fully ready to go back on should I need but typically a couple of the studs snapped in the removal process. I’ve got the out but now need replacements.

anyone know what thread gauge and exact sizes the studs are?
They look to be M8 x 35mm but was hoping someone would know exact ones (with bolts) I needed?

Thanks in advance.

When I had my RS3 and needed to fit the original cats I replaced all the studs with these
