This kit allows you to switch from the CP4 injection pump that come from the factory on the 2011-2016 LML Duramax trucks, to an earlier model higher volume CP3 injection pump. Failure of the CP4 pump almost always results in damaged injectors and a very costly repair bill. Converting to a CP3 injection pump will not only add to your reliability, but you will also have more flow potential.
Replacing your stock Manifold and Up-Pipes should be your first step in building a high performance exhaust system. These exhaust manifolds were co-designed by Honeywell (Garrett) and PPE using CAD software to maximize flow characteristics.

Add an Exergy injection pump of your choice to make the kit complete!
This is an upgrade to the factory upper coolant hose going to the radiator. We make ours out of 304 Stainless Steel so you can be worry free of rust and deforming as you would get from either steel or aluminum. We can add 1/8"NPT bungs as necessary so that you can monitor temp or pressure with an auxiliary gauge.
The 584-3-HSP is best known as the Deluxe Max Air Flow Bundle for the 2015-2016 LML Duramax-equipped Chevrolet and GMC trucks. This bundle kit is the way to go if you are looking to get everything that HSP Diesel makes for the LML to increase and maximize performance.
BD's Screamer line of turbos offer drop-in, stock-appearing units that add an additional punch in power without major modifications to intake or exhaust systems.
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.
