Exhaust Manifold Kit for Dodge Ram (2009-2024) 5.7L Hemi

Upgraded Exhaust Manifold Kit for 2009-2024 Dodge Ram 1500, 2500, 3500 (5.7L HEMI / DS, DJ, D2, DC)

What it Does: Replaces the warp-prone factory exhaust manifolds with a high-silicon ductile iron casting and an upgraded fastening system to permanently resolve chronic exhaust tick and gasket failure.

The Stock 5.7L HEMI Exhaust Manifold Failure

The 5.7L HEMI engine generates extreme exhaust gas temperatures, causing the factory cast-iron manifolds to undergo rapid, severe thermal expansion and contraction. Because the OEM mounting design restricts this natural movement, the rear manifold bolts experience excessive shear stress, eventually snapping off flush with the cylinder head. This creates a highly audible exhaust tick, compromises the exhaust gasket seal, reduces cylinder scavenging efficiency, and leads to inaccurate O2 sensor readings that negatively affect fuel trims.

The Engineering Solution

This upgraded manifold kit is engineered from high-silicon ductile iron, vastly improving the material's yield strength and thermal fatigue resistance compared to stock components. The critical upgrade lies in the proprietary hardware: extended fasteners paired with precision-engineered spacers allow the manifold to thermally expand and contract without transferring shear load to the bolt heads. Additionally, the heat shield features independent mounting locations, entirely isolating it from the main manifold-to-head fasteners. A thicker flange and thicker runner wall design further guarantees resistance to heat distortion and warping under heavy engine load.
