Front pipe/Manifold Studs

Can anyone tell me where to get the studs to hold front pipe to manifold, my local Vx dealer is an absolute :crazy: and useless.

I'm having the flexi that has split causing the front and cat to be two pieces(rattling the studs out with it) welded as a solid pipe for now.

Cheers
