Part of the reason stainless steel headers crack is from Chloride stress cracking corrosion. They will all crack due to this just some sooner that others even inconel will crack from it. The stress from heat distortion, the heat itself and the exposure to chlorides (road salt dirty rainwater etc.) will cause this type of corrosion. It is not notcible like general or pitting corrosion the metal will just crack at a high stress point. If these headers are new before they are coated IE never been exposed to rain water and road salt. then the coating should prevent or at least prolong the time until the headers crack.
