ATS Pulse Flow Exhaust Manifold (2019–2024 Ram 2500/3500 6.7L Cummins)

Keep your 2019–2024 Ram 6.7L Cummins on the road and out of the shop with the ATS Pulse Flow Exhaust Manifold—an engineered, direct-fit upgrade designed to correct the common warping, shrinking, and cracking issues seen with the factory cast-iron manifold.

Built with ATS’s patented Pulse Flow geometry and high-grade D3 High Silica Moly (HSM) cast iron, this manifold improves exhaust efficiency by reducing backpressure and helping lower EGTs—while supporting faster, more consistent turbo spool-up.
