Flattened Exhaust Manifold – Left Side | 5.7L HEMI (2009+)

Restore your HEMI engine with a long-lasting solution to one of the most common exhaust problems found on 5.7L HEMI-powered Dodge, RAM, Jeep and Chrysler vehicles.

Unlike a standard replacement manifold, our flattened exhaust manifold has been precision-machined after production to restore a perfectly flat sealing surface. Factory exhaust manifolds often warp after years of repeated heating and cooling cycles, leading to broken mounting bolts, ticking noises during cold starts and exhaust leaks. By machining the mounting flange perfectly flat, these common issues can be permanently addressed while retaining the original OEM fit.

Why Choose a Flattened Exhaust Manifold?

Over time, the original exhaust manifold expands and contracts under extreme temperatures. This can cause the flange to warp, placing additional stress on the mounting bolts and eventually resulting in:

• Broken exhaust manifold bolts
• Exhaust leaks
• HEMI ticking noise during cold starts
• Reduced sealing between the cylinder head and manifold
• Repeated gasket failures

Our manifolds are professionally machined to restore a perfectly flat mounting surface, providing a much better seal than a warped original manifold and helping prevent the same problem from returning.

Customize Your Repair

To make your repair as easy as possible, you can choose additional installation components directly from the product options before adding the manifold to your cart.

OEM Exhaust Manifold Hardware Kit (Optional)

Choose the OEM Hardware Kit if you want to replace all mounting hardware during installation.

The kit contains 100% Genuine Mopar components, including the correct bolts, studs and flange nuts required for a factory-quality installation. Unlike generic aftermarket hardware, genuine Mopar fasteners are manufactured to withstand the extreme temperatures and thermal cycles produced by the 5.7L HEMI engine, ensuring the correct fit, proper clamping force and maximum durability.

OEM Exhaust Manifold Gasket (Optional)

You can also add a Genuine Mopar exhaust manifold gasket to complete your repair.

Installing a new OEM gasket together with a flattened manifold helps ensure the best possible seal and significantly reduces the chance of future exhaust leaks. Reusing an old gasket is not recommended during manifold replacement.

Suitable for selected vehicles equipped with the 5.7L HEMI V8 (2009+).
