AFE BladeRunner Exhaust Manifolds with Up-Pipes (01-04 6.6L Duramax Sierra 2500 HD)

Outflows the factory exhaust manifolds by 6%, improving performance and throttle response

• Compatible with factory up-pipes which allows for easy installation.
• Eliminates the flow restricting pinch of the factory drivers-side manifold
• The machined ports match the factory gasket openings which maximizes exhaust flow
• 1/8" NPT exhaust gas temperature ports (EGT) are incorporated into the exhaust manifolds for gauges or testing equipment
• Durable cast ductile iron construction
• Manifold mounting hardware is included for a hassle-free installation.

Construction:

• These unique up pipes are constructed of 2" mandrel-bent 304 stainless steel tubing with a .120" wall for strength and durability.

2" Inner Liner Flex Pipes:

• The down-pipes utilize heavy duty 2" flex tubes with internal inner liner.

Leak-Free Seal:

• High quality 3/8" thick flanges are used for a complete 360 degree sealing surface.

Machined Ports:

These manifolds have both the inlet and outlet ports machined to match the factory gaskets. This allows for maximum flow, without compromising gasket performance.

Auxiliary Ports:

An Exhaust Gas Temperature (EGT) probe port is incorporated into each manifold for easy installation of gauges or testing equipment. There are three additional cast-in bosses provided to allow for alternate testing points.

Hassle-Free Installation:

These manifolds are compatible with the stock up-pipes, which allows the manifolds to be installed without having to remove the turbocharger down-pipe or the up-pipes.
