Product Description

The ATS Diesel 204-950-2464 PulseFlow Exhaust Manifold is the definitive direct replacement for the failure-prone factory MOPAR 68444858AA on 2019-2024 Ram 2500/3500 pickup trucks with the 6.7L Cummins. The stock one-piece cast-iron manifold is notorious for warping, shrinking, and snapping studs under repeated heat cycles - especially under sustained towing loads. ATS solves this with a multi-piece design that allows each section to expand independently, eliminating stress on the cylinder head and fasteners entirely.

Built from D3 High Silica Moly iron and finished with an advanced ceramic coating rated to 2,000°F, this manifold not only outlasts the factory unit but actively improves efficiency by lowering EGTs and spooling the turbo faster through its patented Pulse Flow geometry. This is the premium kit variant, including multi-layer gaskets and hardware for a complete, hassle-free installation. Backed by ATS's 5-year / 500,000-mile warranty, it's the last exhaust manifold your 5th Gen Ram will ever need.
