A Smarter, Stronger Manifold for Your 5.9L Cummins

If you’ve ever dealt with a cracked stock manifold on your 2003–2007 Dodge RAM 2500 or 3500, you know how frustrating that weak point can be. The ATS T4 2-Piece Pulse Flow Exhaust Manifold Kit is built to solve that problem while delivering real performance benefits along the way. Made from cast high-silica moly, this manifold is far more resistant to heat fatigue and cracking compared to the factory setup. The pulse flow design improves exhaust gas velocity, which helps your turbo spool quicker and more efficiently. It’s also finished in a black ceramic coating that helps manage under-hood temps and adds a clean, durable look to your engine bay.

Built to Perform, Designed to Last

This manifold features a T4 turbo flange and is configured for non-wastegated turbos, making it a solid choice for street-driven trucks, towing rigs, and mild performance builds. The patented ball flange design helps reduce stress between the manifold and turbo, improving sealing and preventing warping over time. ATS includes everything you need for installation, and in most cases, your existing gaskets can be reused if they're in good shape. Whether you’re replacing a failed factory part or upgrading for performance, this two-piece manifold offers a strong, reliable foundation for better turbo performance and long-term durability. It's the kind of upgrade that not only solves a common problem but also improves the way your Cummins-powered truck runs and feels on the road.
