Description
BD focused on solving one of the Ford 6.7L common failures: the exhaust manifolds. Crafted with a heavy-duty 0.275″ thick-walled Hi-Silicon ductile casting, these manifolds are 75% thicker to combat cracking due to high exhaust temperatures. Thermal durability has been improved with longer exhaust studs and spacers, plus thicker, more durable machined bolting flanges. Fully EGR compatible, BD’s exhaust manifold set is the perfect replacement for reliability and peace of mind—especially when paired with BD’s Scorpion Turbo Kit.
