CastFlow Manifolds & Up Pipes

(1 customer review)


Brand: ProFab Performance



This is the newest CastFlow series manifolds and 2″ up pipes. Expect greater hp, quicker spool up, and lower egts with these. The standard sets comes WITHOUT an EGR provision, but you can add one above if needed. 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.
