Manifolds Built to Take the Heat Without Cracking

Factory cast manifolds are thin, single-piece castings that crack at the divider walls and warp at the flanges under towing and daily heat — opening leaks that drop boost and raise EGTs. These high-flow stainless and HSM manifolds use stronger alloys and expansion joints to move with the heat instead of fracturing. The 3.5L EcoBoost has its own issue: the OE manifold only uses 8 of the head's 11 stud locations, so it warps and snaps studs — the kits here fix that too.

Fits these trucks

  • Ford 7.3L, 6.0L, 6.4L & 6.7L Powerstroke — exhaust manifolds, manifold kits, turbo & tail pipes
  • Ford F-150 & Lincoln Navigator 3.5L EcoBoost (gas) — exhaust manifold kits

Frequently Asked Questions

Why do factory Powerstroke manifolds crack?
Thin cast iron expands and contracts every heat cycle. Towing and daily heat fatigue it until it cracks at the divider walls and warps at the flanges, leaking exhaust, dropping boost, and raising EGTs.
What does a high-flow stainless manifold get me?
Stronger 304/HSM construction and expansion joints that move with the heat instead of cracking, plus larger runners for less backpressure and lower EGTs.
Why do EcoBoost manifolds fail?
The OE 3.5L manifold only uses 8 of the head's 11 stud locations, so it warps, snaps studs, and blows gaskets. Upgraded kits use the full pattern.
