This is the CastFlow Xtreme series manifolds and 2" up pipes.

These are for trucks WITHOUT conventional downpipes. Typical use is twins and hood stack trucks. The passengers side up pipe almost excactly matches the drivers side.

Expect even greater hp, quicker spool up, and lower egts with these.

The standard sets comes WITHOUT an EGR provision.

They are available with ceramic coated that will hold up to 1600 degrees. The coating improves performance a little and drops underhood temps. Our ceramic coating is a heat coating only, not a rust preventative.

LMM trucks require a coolant line relocation fitting found in the appropriate section. No gaskets included.

2015's may need a small spot on the passengers side manifold ground for clearance.
