With stainless, I've seen a nut get seized just being chased halfway down the treads. Nothing there to stop it, just did. Using anti-seize is a must. Although I've heard about some issues with heat, I can all depend where on the exhaust they're being used. Bolts near a turbo are going to be way hotter then at the back of the vehicle.
