BD Exhaust Manifold Set – Ford 6.7L Power Stroke

BD focused on addressing one of the most common failure points on the Ford 6.7L Power Stroke: the exhaust manifolds. These heavy-duty manifolds are crafted from 0.275" thick-walled high-silicon ductile cast iron, making them 75% thicker than stock to combat cracking caused by extreme exhaust temperatures. Thermal durability is further enhanced with longer exhaust studs, black oxide coated spacers, and precision-machined thick bolting flanges. Designed to be fully EGR compatible and 50-state legal, this manifold set offers long-term reliability and peace of mind.
