From what I've been told the reason it cracked is due to a bad weld, it was too hot or something and has thinned the steel in that area
though had an amazing guy help me yesterday by welding the manifold up for me while it was 'still' on the car with all the turbo and parts in place 
:!: I think SSA would be able to make good parts IF they spent alittle more on the welding, all their stuff is single not double tiged, n't ask me what that means though but apparently it means its not as strong
