FULL-RACE FORMLINE CAST STAINLESS EXHAUST MANIFOLDS FOR GEN 1 (2011-2016) 3.5L ECOBOOST

The Full-Race Formline Cast Stainless Exhaust Manifolds for the Gen 1 (2011-2016) Ford Ecoboost 3.5L engines are a direct replacement for the OEM exhaust manifolds. Due to some inherent flaws, the OEM manifolds are known to warp or crack, resulting in costly repairs. Besides that, the OEM manifolds don't flow very well and present fitment challenges when used with larger turbos. The Full-Race Formline manifolds solve these issues. Cast from 347 Stainless Steel, the Formline manifolds resist warping and cracking.

The OEM Ecoboost exhaust manifolds don't flow very well due to some limitations in their design. Let's face it- the OEM manifolds aren't designed for power. We've started with a clean-sheet design to ensure that the Full-Race Formline manifolds outflow all available manifolds. We've opened up the outlet port to closely match the inlet port on the exhaust side of the turbochargers. In addition, we've increased the diamter of the runners for maximum flow.

The Formline manifolds feature a completely new design than the OEM exhaust manifolds. The OEM manifold utilizes a single runner, which reduces flow and increases backpressure. By separating the exhaust flow into two distinct runners, we've increased the runner area by over 32%! We've also designed these manifolds to fit with Garrett PowerMAX turbochargers without the need to modify them for fitment.
