ATS Pulse Flow Exhaust Manifold for 2019-2024 RAM Pickup 6.7L Cummins. The Ultimate Direct Replacement for MOPAR 68444858AA

Keep your 2019-2024 RAM Pickup 6.7L Cummins on the road and out of the shop.

The ATS Pulse Flow Exhaust Manifold is the definitive fix for the common warping, shrinking, and cracking issues found in factory MOPAR cast-iron units.

Since 1995, ATS Diesel has led the industry in exhaust gas technology.

By combining patented Pulse Flow geometry with high-grade D3 High Silica Moly (HSM) cast iron, this manifold not only outlasts the stock version but actively improves efficiency by lowering EGTs and reducing back pressure.

Key Product Benefits

• Advanced Ceramic Coating: Each manifold is finished in a high-temp ceramic coating providing substrate protection up to 1600 degreeF and environmental protection up to 2000 degreeF. This clean black finish traps heat inside the manifold to reduce extreme under-hood temperatures while effectively preventing corrosion and rusting.
• Prevent Manifold Failure: The stock MOPAR 68444858AA manifold is prone to shrinking, which often snaps studs and causes leaks. The ATS multi-piece design allows for thermal expansion without stressing the cylinder head of your 2019-2024 RAM Pickup 6.7L Cummins.
• D3 HSM Material: Constructed from High Silica Moly iron, designed to withstand the extreme heat cycles of heavy towing without cracking or becoming brittle.
• Lower EGTs & Better Flow: The patented internal bell mouth design smooths out exhaust pulses, increasing velocity and improving turbocharger spool-up.
• Reliable Clamping: Designed to work perfectly with ATS 12.9-grade black oxide studs for maximum clamping force.
