01-16 Chevy/GMC Duramax Ceramic Billet Manifolds - HSP Diesel - 019-HSP-C

Why Would You Need the HSP Diesel Coated Billet Manifolds?
The factory manifolds are restrictive from the get-go. HSP Diesel noticed quickly that these needed to be addressed if you wanted to make more power. The factory manifolds are also known to fail due to cracks, warping, and broken bolts. The HSP Diesel Manifolds address all of these issues while looking better and adding power.

What do the HSP Diesel Coated Billet Manifolds do differently?
To start the HSP Diesel Coated Billet Manifolds are machined from 1018 steel. This means you have the maximum flow due to a more open port design increasing the flowability of the exhaust and the common flow restriction that is found in the driver's side manifold.

The design of the HSP Diesel Coated Billet Manifolds is also low profile meaning that you get some extra room if you need to worry about the custom routing of parts. The HSP Diesel Coated Billet Manifolds work with factory-style Up-pipes and come ceramic coated for superior heat protection that is good up to 2000 degrees.
