FITS: 2017 - 2020 Ford F-150 & Raptor 3.5L EcoBoost

Given the high rate of failure of the OEM Ecoboost exhaust manifolds, we wanted to develop the ultimate Raptor and F-150 turbo manifold to solve these problems once and for all. Hundreds of engineering hours iterating from 3D scanning to CAD to 3D printing led to our final design that keeps the exhaust pulses from each cylinder from interfering with each other (even at high power levels) and increases reliability.

MAKE MORE POWER, AVOID COSTLY REPAIRS

The Full-Race Formline® Cast Stainless Exhaust Manifolds for the Gen 2 (2017-2020) Ford Ecoboost 3.5L engines are a direct replacement for the OEM cast iron exhaust manifolds. Due to some inherent flaws, the OEM cast iron manifolds are known to warp or crack, resulting in costly repairs. Besides that, the oem cast iron manifolds don't flow very well and present fitment challenges when used with larger turbos. The Full-Race Formline® cast stainless manifolds solve these issues. Cast from 347 stainless steel, the Formline® manifolds resist warping and cracking. These manifolds are a 100% bolt-on replacement - including new OEM gaskets, studs and nuts.

For years 304 stainless steel has been a go-to material for sturdy, long lasting turbo manifolds and other motorsport exhaust components. It's known that Ford EcoBoost 3.5L owners push their engines hard and demand extreme reliability under towing and off-road conditions - failure is not an option. That's why we’ve opted for an upgrade from 304 stainless steel to 347 stainless steel. 347 stainless is commonly found anywhere high temperature and highly corrosive environments exist - from refinery equipment to jet engine parts. This material maintains superior resistance to any type of failure under high temperature operating conditions.

FULL-RACE FORMLINE GEN 2 EXHAUST MANIFOLD FEATURES

  • Designed to fit the 2017-2020 Ford F-150 with 3.5L Generation 2 Ecoboost Engines
  • 100% Bolt-On Replacement
  • Investment Cast from 347 Stainless Steel
  • Individual Runner + Merge Collector Design
  • Reduced Back Pressure → Increased Flow
  • Turbine Outlet Port Matched to OEM Gen2 Turbo (41mm)
  • Designed to Fit Larger Turbos (unlike other manifolds)

BETTER MATERIALS FOR ULTIMATE RELIABILITY

Cast iron starts to fail at 1500F maximum temp but starts to warp much earlier than that, especially when the material is thin. Furthermore if you compare the thickness of the Formline® manifold flanges to the OEM flange - the difference is clear. In addition to being 1/2" thick vs 3/8" thick, the Full-Race Formline® Ecoboost manifold is cast from 347 stainless steel. This material is able to withstand temps of up to 950C / 1740F, making it ideal for an EcoBoost exhaust manifold.

INCREASED FLOW = MORE POWER

The OEM Ford Cast Iron 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. The team at Full Race began with a clean-sheet design to ensure that the Formline® cast stainless 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 diameter of the runners for maximum flow.

INCREASED FLOW CAPACITY

The OEM log manifold exhaust chamber has an incredibly small slot-shaped passage. It’s at its narrowest after the front two exhaust ports, right before the third. When this area is converted to an equivalent ‘hydraulic diameter’ it measures only 31.4 mm. Ford expects two cylinders worth of exhaust flow to cram its way through that duct! For reference, that's smaller than the runner we would use for (1) cylinder on a 1.6L turbo manifold.

Another shortcoming of the OEM log manifold design is the mismatch between the 33mm OEM manifold's outlet and the 41mm turbocharger turbine inlet. The OEM log manifold has a smaller outlet than the inlet of the turbine housing - meaning exhaust flow is forced to run through a sharp 90° step! This is the least efficient and most restrictive way of joining the flow of two dissimilar sized ducts.

We increased the Formline® manifold outlet from 33mm to 41mm to match the size of the entry to the turbine housing (also 41 mm).  This small change translates into a 41% increase in outlet area.  The next task was to give each cylinder a little bit more breathing room by increasing the runner cross sectional area. Our new runners start by equalling the area of the exhaust ports, and gradually taper down to a minimum diameter of 31.4mm each. Compared to the OEM measurement of 29 mm that may not sound like much but remember the Formline® manifolds have a min diameter of 30 mm for EACH cylinder!  All this will result in reduced backpressure and increased turbocharger efficiency.

FULL-RACE'S INCONEL EXHAUST MANIFOLD STUDS

At Full-Race we know Ecoboost performance. The first step to ensuring that your truck makes all of the boost it's supposed to is to avoid the common exhaust leaks for on the 3.5L manifolds.

As an added bonus all new Formline® Manifolds and turbo kits will include these studs.
