HSP Diesel Coated Billet Manifolds

Why Would You Need the HSP Diesel Coated Billet Manifolds?

_x000D_ 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._x000D_

What Do the HSP Diesel Coated Billet Manifolds Do Differently?

_x000D_ The HSP Diesel Coated Billet Manifolds are machined from 1018 steel. This allows for maximum flow due to a more open port design, which eliminates the common flow restriction found in the driver's side manifold. The low-profile design also offers additional clearance for custom routing. These manifolds are compatible with factory-style up-pipes and come ceramic coated for superior heat protection—rated up to 2,000°F._x000D_
