BladeRunner Ported Ductile Iron Exhaust Manifold RAM 1500 (DT) 19-24 V8-5.7L HEMI

These manifolds have both the inlet, and the outlet ports machined to match the factory gaskets. This allows for maximum flow, without compromising gasket performance. These manifolds have 25% Thicker walls than the crack-prone factory manifolds. The increase in thickness increases the rigidity of the manifolds and make them much more durable than the OE manifolds. These manifolds bolt directly to the factory y-pipe for an easy installation.
