Exhaust Manifold Set PowerStroke 6.4L - Ford 2008-2010 F-250/F-350/F-450/F-550 1990 Direct Friction AllomaticThe 6. 4L manifold set is crafted with a heavy duty 0. 25" thick walled Hi Silicon ductile casting, this makes these manifolds thicker to combat cracking due to high exhaust temperatures. To maximize exhaust flow, computational fluid dynamics were used to optimize flow and exhaust port geometry. BD's exhaust manifold set is the perfect replacement for reliability, performance and peace of mind. Ports are gasket matched to maximize exhaust flow
