Just a newbie question, I assume if the cast is of good quality, would wall thickness of the base + density of the cast make it more resistant to cracking than a tubular steel manifold when going through 1000s of heat cycles?

I would assume steel like most metal loses integrity over time when heat cycled at the temperatures that an exhaust manifold reaches?
