aFe Power is proud to introduce BladeRunner ported ductile iron exhaust manifolds for 2001-2016 GM Diesel Trucks with V8-6.6L (td) LLY/LBZ/LMM/LML engines.
- 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.
- 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.
- 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
