If you have a 0.001" gap between two particles it's way harder to blow through it than with a .040" gap. And if it really does happen, the .040" gap leaks significantly more than a .001" gap.



This is the key. If you have no gasket, it can't fail. As soon as you use a gasket you're doomed. The first time you tighten the flange to the head with a gasket you bend/ warp it, because the gasket compresses. You dont need gaskets if you made the exhaust right.
