Exhaust studs - what size?

[Alex]

I'm missing two manifold-downpipe studs.

Can't be arsed with VW prices as I'm getting a full system soon (hopefully)

What size do I need?

[Dan]

M10, but they need to be high tensile.

Seems weird that G40s have M10 exhaust studs, thats massive. Anyone know why?

[Dan]

The flange is much bigger than a normal polo one, which helps explain in.

manifold to downpipe stud - i use threaded bar and cut it down

[Alex]

Cool, I'll see if I can get a set locally without a trip to the stealers. Judging by how I've got the two new ones, I guess they don't like to be reused. It's the two old ones which have dropped out.

mine broke when taking them out so i just used bolts and they've never came out

[Dan]

Nothing wrong with using them again, providing the threads are ok.

[Alex]

Yeah mine had been re-used already though, I guess they'd been over-tightened at some point.
