A Solid Fix for a Common Problem

If you're running a 1998.5–2002 Dodge RAM with the 5.9L 24-valve Cummins, you've probably heard stories—or lived them—about cracked factory exhaust manifolds. The ATS T4 3 Piece Pulse Flow Exhaust Manifold Kit is designed to end those headaches and give your turbo system a solid performance bump in the process. Built from high silica moly cast material, this manifold holds up under the heat and pressure that comes with diesel work. Its three-piece pulse flow design helps maintain exhaust gas velocity for better turbo spool, smoother throttle response, and a more efficient engine overall. Whether you're towing, hauling, or just enjoy putting your foot into it, this setup delivers the durability and performance your truck deserves.

Smart Design That’s Easy to Install

ATS didn’t just make this manifold stronger—they designed it with real-world use in mind. The T4 turbo flange fits a wide range of setups, and the non-wastegated configuration keeps things simple for performance-focused builds. A patented ball flange helps absorb stress between the manifold and turbo, reducing the chance of leaks or warping over time. It’s also ceramic coated in black, which helps control under-hood temperatures and adds a clean, finished look to your engine bay. The kit includes everything you need for installation, and if your current manifold gaskets are still in good shape, you can reuse them. This is a bolt-on upgrade that solves a known problem while giving your Cummins-powered RAM better flow, reliability, and peace of mind.
