2001-2016 Duramax Ceramic Billet Manifolds (019-HSP-C)

Why Would You Need the HSP Diesel Coated Billet Manifolds?
The original manifolds are pretty limiting, but HSP Diesel swiftly realized they needed a makeover for more power. They prone to breaking with cracks, warping, and broken bolts. Luckily, the HSP Diesel Manifolds tackle these problems while also boosting power and adding some aesthetic appeal.

What do the HSP Diesel Coated Billet Manifolds do differently?
The HSP Diesel Coated Billet Manifolds are machined from 1018 steel, ensuring maximum flow with an open port design that increases exhaust flow and reduces common restrictions in the driver's side manifold. Its low-profile design also provides extra space if you need to worry about the custom routing of parts. Plus, these manifolds work with factory-style Up-pipes and are ceramic coated for superior heat protection up to 2000°.
