aFe BladeRunner Exhaust Manifold RAM 1500 (DT) 19-24 V8-5.7L HEMI

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

• Outflows the factory exhaust manifolds by 15%, improving performance and throttle response
• The machined ports match the factory gasket openings which maximizes exhaust flow
• Manifold mounting hardware is included for a hassle-free installation.
• 25% Thicker walls for increased rigidity and crack resistance
• Durable cast ductile iron construction

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.
