The engine at the heart of your Mercedes-Benz vehicle relies on the exhaust system to safely disperse of the noxious fumes generated when it burns the air-and-fuel mixture that feeds internal combustion. That exhaust system is composed of many parts, with the manifolds and headers being among the most essential. They're often used as synonyms, since they serve the same purpose, but they're different parts.

The Difference Between Manifolds and Headers

An exhaust manifold gathers the exhaust gases from ports in the cylinder heads and then sends them onto through the exhaust system. They're typically made of thick cast iron and feature short inlets that come together to a single collection point. Since their design and material make them extremely durable, they're most common.

Headers, however, are usually made from thin stainless steel tubes that allow the gases to flow more freely than they would with a manifold. Since they create less exhaust backpressure than manifolds, they make it easier for your engine to breathe. They're typically found on performance-oriented models.

How to Spot Problems With Exhaust Manifolds and Headers

Eventually, though, wear and tear can cause even the best manifolds or headers to start to go bad. Signs of trouble include:
