BMW M57 Exhaust Manifold Cast Iron

BMW M57 Top Mount Exhaust Manifold

The BMW M57 Top Mount Exhaust Manifold is based on the factory BMW M57 D1 / M57N D2 cast iron exhaust manifold featuring the original 3-bolt turbo flange. It is commonly used as the foundation for BMW M57 top mount turbo conversion projects.

When installed upside down, this manifold allows the turbocharger to be positioned above the engine, creating additional clearance around the chassis, steering components, transmission and frame rails. This configuration is widely used in engine swap, off-road, overland and custom diesel performance applications.
