As welshpug says it's probably weight and flex causing that. Stainless doesn't like to flex, it's pretty hard stuff. It doesn't absorb heat well either so if you do heat it it tends to stay localized and that can cause cracking. I don't want to put the jod on ZX_Volcanes manifold but we warmed the whole thing up in the forge till it was glowing orange as evenly as possible to try and stress relieve it and hopefully minimize the chances of what's happened to yours. The brackets on the turbo also support it's full weight without relying on the manifold at all.
