Full-Race 2021+ Ford F-150 & Raptor 3.5L EcoBoost Formline® Turbo Manifolds
Next-Gen Power, Proven Formline® Engineering
Ford's third-generation 3.5L EcoBoost is the strongest and most advanced yet, but even this refined engine has one leftover weak link: the exhaust manifolds. 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.
Each 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.
Real Results (dyno)
Stock truck (no tune): 360 WHP / 442 WTQ. Formline® manifolds + MPT tune: 480 WHP / 593 WTQ — up to +120 WHP / +151 WTQ over stock when tuned.
