Exhaust pipe to manifold bolt size

[Cornbread]

I need to pick up few bolts today to install my new bc broncos 2 in 1 exhaust kit. Anybody know the bolt size that bolts the exhaust pipe to the stock manifolds? Not manifold to block. There are four.

My BC kit had the nuts for the studs and iirc, even had new studs. Are you sure you don't have them in the hardware pack?

I did see a few nuts floating around in the pack but i assumed they went with the clamps. Did not see any studs...

Any future work you do or will have done will be a lot easier with the OE studs. I think they're 7/16" diameter. The best studs have an integral hex nut to screw them into the manifold and keep them there while removing the nut that secures the exhaust pipe flange.
