Castflow Manifolds w/ 2 1/4″ Up Pipes

Description

This is the newest CastFlow series manifolds and 2 1/4″ 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.

Will NOT work with standard downpipe!

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.
