High-Performance Exhaust Upgrade. The ATS Diesel Performance Pulse Flow Exhaust Manifold is engineered to enhance the power, durability, and reliability of your 5.9L Cummins engine. Featuring a T3 turbo flange and 2-piece design, this manifold is ideal for non-wastegated turbo setups, offering improved exhaust flow and reduced backpressure. It's a dependable upgrade for towing, performance builds, and long-haul durability.
Construction and Appearance. Manufactured from advanced D3 high-silicon molybdenum (HSM) material, the Pulse Flow manifold offers superior strength under extreme heat and pressure. The patented ball flange design eliminates common cracking issues, while the black ceramic coating adds thermal resistance and protects the manifold from corrosion over time. The two-piece design also helps to reduce warping and improves fitment during installation.
Installation. Installation is moderately difficult and may require mechanical experience or professional assistance. All necessary components are included, and the design allows for a straightforward replacement of the factory manifold.
Application. This ATS Diesel Performance Pulse Flow Exhaust Manifold fits 2003 to 2007 RAM 2500 models equipped with the 5.9L Cummins diesel engine.
