Kind of beyond the scope of this thread but I would recommend 1.63" primaries for 400WHP. We offer both sizes. Boost creep is an issue with "elephant nose" design headers. We addressed that issue by taking a smooth bend off of each bank to a Y joint terminating in a common tube to the waste gate. Dual waste gate option is optimal for true twin scroll turbo use. Precise control of boost using 38mm WG for each bank.
