aFe 01-04 GM V8-6.6L LB7 Twisted Steel Manifold w/ Up Pipe

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 utilizes 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 the 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.
