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.

Key Features & Benefits

• Direct Replacement: Replaces OEM MOPAR part 68444858AA.
• High-Temp Ceramic Coating: Substrate protection up to 1600°F and environmental protection up to 2000°F; helps retain heat in the manifold and reduce under-hood temps.
• Multi-Piece Design: Allows for thermal expansion to help prevent leaks, broken studs, and cylinder head stress.
• D3 High Silica Moly (HSM) Cast Iron: Built to handle extreme heat cycles and heavy towing without becoming brittle.
• Pulse Flow Internal Geometry: Smooths exhaust pulses to increase velocity and improve turbo response.
• Premium Clamping Support: Designed to work with ATS 12.9-grade black oxide studs for maximum clamping force.
