Let us all know how much they end up costing. I remember some people were selling the cast iron manifolds for like 1k! What kind of retard would you be to spend that much on a pos manifold? Its worth 3-400 bucks at max. It flows horribly, but if its cheap enough, its good for a "Ghetto" single kit. At 1k, its ludicrous, especially considering you can get the HKS Manifold with the HKS GT Wastegate for like 2k!
