BMW M5 Headers

If you know the ins and outs of an exhaust system, then you know what an exhaust manifold does. What factory headers do for one, especially for the manifold in a BMW M5, may not be as apparent. Put simply, they're bolt-on accessories that eliminate any back pressure produced during your engine's exhaust stroke. In short, a header makes it easier for the engine to push exhaust gases out of its cylinders. The result is, of course, improved engine performance. But how does an original exhaust header work in a BMW M5 specifically? It's straightforward. During the car's engine's exhaust stroke, its exhaust valve opens, and pistons push the gases out of the cylinders. However, if there's any resistance to that push (called "back pressure"), the engine can lose power. Headers solve this problem. They equip each cylinder with an exhaust pipe all its own. The pipes get cut and bent so that they're all the same length, guaranteeing that each cylinder's gases arrive in a single, large collector pipe spaced out equally. That way, there's no back pressure generated by the cylinders that share it. Want to upgrade the engine in your sports sedan? You're in luck.
