BD Diesel Performance's manifolds for the 2011-2014 6.7L Power Stroke are crafted with a 0.275-inch thick walled Hi-Silicon ductile casting, which makes the manifolds 75 percent thicker to resist cracking that comes as a result of those high exhaust gas temperatures (EGTs) commonly experienced for these model years. Thermal durability is improved with longer exhaust studs and spacers, along with with thicker and more durable machined bolting flanges.
In maximizing exhaust flow, exhaust port sizes have been increased to match gasket sizes. BD's fully EGR-compatible exhaust manifold set is the perfect replacement to give you reliability, performance, and peace of mind with your truck. The manifolds come as a kit, available for $445.
