BD 1045296 Exhaust Manifold Set

The BD-Power 1043007 Exhaust Manifolds are an improved replacement to the weak factory exhaust manifolds on your 2011-2014 Ford 6.7L Powerstroke. Constructed from heavy duty 0.275" Thick-walled Hi-Silicon ductile casting, these manifolds are 75% thicker than stock, helping to reduce the chance of cracking due to high exhaust temperatures. With thicker flanges, longer exhaust studs and spacers, thermal durability is far greater than the factory manifolds. 

BD doesn't stop there, they optimize exhaust flow with the use of computational fluid dynamics and also increase the port size to match the gaskets. Included with the 1043007 are the right & left manifolds, studs, spacers, and exhaust manifold gaskets for a complete installation.
