But the main reason I hear that stainless cracks is due to the heating and cooling processes it goes through if its not been made to a high standard.
problem is. the stainless manis arent shielded against water. drive the car in this country and water will very quickly toch the manifold when hot.
Stainless 304 is prone to carbide precipitation when at high temps so it's not ideal, 321 would be a more suitable choice. Wall thickness is also very important. Personally with all the cheap s/s manifolds we've had countless problems hence we made a mild steel version which is soon to be released
