Take control of your boost with the Vinny Fab T4 Twin-Scroll Turbo Manifold, precision-built for the FD3S RX-7. Engineered with proper waste-gate placement for unbeatable boost control, this manifold eliminates over-boost and boost-creep issues common with poorly designed headers.
The waste-gate runners are positioned directly in the exhaust flow and shaped with tear-drop inlets, allowing gas to exit efficiently for rock-solid boost stability — even under heavy load or high boost.
