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, this makes
these manifolds 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. To maximize
exhaust flow, computational fluid dynamics were used to optimize flow and
exhaust port sizes have been increased to match gaskets. Fully EGR
compatible, BD’s exhaust manifold set is the perfect replacement for
reliability, performance and peace of mind.
