Description
This is the newest CastFlow series manifolds and 2″ up pipes. Expect greater hp, quicker spool up, and lower egts with these. LMM trucks require a coolant line relocation fitting found in the LMM section. New manifold bolts are included.
2015’s may need a small spot on the passengers side manifold ground for clearance.
Gasket sets may be added above.
Gasket sets will include 2 manifold/header gaskets, 1 double upper up pipe gasket, and 2 lower up pipe gaskets.
Our ceramic coating is a heat coating only, not a rust preventative.
Due to the extreme temperatures possible, ceramic coatings will not be covered by warranty.
Please note: We use a good used factory egr riser on the passenger side up pipe.
These are made to order, so could take 4 – 6 weeks
