I'm pretty sure they're 8 mm (13 mm wrench, sometimes 12 mm). I
wouldn't use stainless - it's not very strong, and will just seize if
you try to torque them tight to eliminate leaks. Exhaust hardware
should basically be considered "one time use." It's only a couple of
bucks in cheap, steel hardware which you can get at pretty much any
decent hardware store (Ace, Do It Best, etc.). No need to pay more, or
travel farther, to an auto store.

The exception is for studs, where it pays to use copper (or more
commonly, copper plated) nuts. Those may be hard to find locally.
