This statement is, I suppose, true and false at the same time. Cars from the factory come with exhaust manifolds. The term "header" is used for labeling an aftermarket exhaust manifold. Same result, same idea. A header just flows air better due to smoother bends, edges, lighter metals, and better quality.
