So who could I ask to make me something like this out of mild steel. But instead of a v band I want a t4 flange for my precision. 2.5" inlets with a 1.875 starter tube for the wastegate topped with a t4 flange out of mild steel. What would be a reasonable price? Was going to buy a complete hot side but I'd rather just by the headers and make the rest to insure everything fits the way I want.
