Built for cost efficiency, the stock castings are known to warp, crack, and restrict flow once heat and boost rise. That's why we built the Full-Race Formline® Turbo Manifolds for the 2021+ F-150 and Raptor.\u003c\/p\u003e\u003cp\u003eEach Formline® manifold is investment-cast from 347 stainless steel, a high-temperature alloy chosen for its strength, heat tolerance, and corrosion resistance (rated to 1740°F \/ 950°C). The outlets are port-matched to the 40mm turbo inlets (a 38% larger outlet area vs the 34mm OEM), eliminating pre-turbo restriction and improving spool. Refined runner geometry reduces backpressure and improves exhaust velocity. The manifolds retain the factory cooled-EGR system for knock resistance under load.\u003c\/p\u003e\u003ch4\u003eReal Results (dyno)\u003c\/h4\u003e\u003cp\u003eStock truck (no tune): 360 WHP \/ 442 WTQ.
