Flattened Exhaust Manifold – Left Side | RAM 1500 DT 5.7L HEMI (2019+)

Restore your exhaust system with a long-lasting solution designed to eliminate one of the most common issues affecting the 5.7L HEMI engine.

This flattened left-side exhaust manifold has been precision-machined after production to create a perfectly flat sealing surface. Unlike many factory manifolds that can warp over time due to repeated heating and cooling cycles, this upgraded manifold provides improved gasket sealing, helping to reduce the risk of future exhaust leaks and broken manifold bolts. Exhaust manifold warping and broken mounting bolts are well-known issues on HEMI-powered RAM trucks.

Manufactured from high-quality cast iron and machined to OEM specifications, this manifold installs in place of the original unit without requiring any modifications.

Why Choose a Flattened Exhaust Manifold?

Repeated heat cycles can cause the original exhaust manifold to distort, leading to:

• Exhaust leaks
• Broken manifold bolts or studs
• Ticking noise during cold starts
• Reduced sealing between the manifold and cylinder head

A professionally flattened manifold restores a perfectly even mounting surface, providing a significantly better seal than a warped original manifold. This greatly reduces the likelihood of recurring exhaust leaks when installed with new gaskets and hardware.

Recommended During Installation

For the most reliable repair, we recommend replacing the following components at the same time:

• OEM exhaust manifold gasket
• Exhaust manifold bolts
• Exhaust manifold studs
• Heat shield mounting hardware

Replacing all installation hardware helps ensure proper clamping force and reduces the chance of future failures.
