ATS Diesel 2049502464 Pulse Flow Exhaust Manifold Kit for 2019-2024 RAM Cummins 6.7L

The ATS Diesel Pulse Flow Exhaust Manifold is the definitive fix for the common warping, shrinking, and cracking issues found in factory MOPAR cast-iron units on 2019-2024 RAM 2500/3500 6.7L Cummins trucks. 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 Features:

• D3 HSM Material construction from High Silica Moly iron designed to withstand extreme heat cycles of heavy towing without cracking or becoming brittle
• Advanced ceramic coating providing substrate protection up to 1600°F and environmental protection up to 2000°F
• Clean black ceramic finish traps heat inside the manifold to reduce extreme under-hood temperatures while effectively preventing corrosion and rusting
• Multi-piece design allows for thermal expansion without stressing the cylinder head
• Patented internal bell mouth design smooths out exhaust pulses, increasing velocity and improving turbocharger spool-up
• Designed to work perfectly with ATS 12.9-grade black oxide studs for maximum clamping force

Complete Kit Includes:

• ATS Pulse Flow Exhaust Manifold
• Turbo Gasket and Hardware
• Cylinder Head Gaskets
• Premium 12.9 Stud Kit
• EGR Gasket Set

The stock MOPAR 68444858AA manifold is prone to shrinking, which often snaps studs and causes leaks. This ATS replacement provides superior durability and performance for diesel enthusiasts who demand reliability under heavy towing loads and performance modifications. Backed by a 3-year limited warranty.
