BD has addressed a common issue with the Ford 6.7L engine—cracking exhaust manifolds—by designing a heavy-duty replacement. These manifolds are made from 0.275″ thick Hi-Silicon ductile casting, making them 75% thicker for improved resistance to high exhaust temperatures. Enhancements include longer exhaust studs, spacers, and more durable machined flanges for better thermal durability. Fully EGR compatible, BD’s exhaust manifold set offers a reliable, long-lasting solution.

The factory exhaust system on the 6.4L Power Stroke is prone to failure over time due to heat and age, leading to issues like exhaust leaks, slower turbo performance, and increased noise and soot. BD’s Exhaust Manifold & Up-Pipe Kit addresses these problems with a more durable and efficient design. The kit includes large-diameter, mandrel-bent 304 stainless steel up-pipes with expansion bellows to reduce turbo restriction. The heavy-duty exhaust manifolds are made from thick-walled Hi-Silicon ductile casting to resist cracking.
