In Latin, the word "manifold" denotes "hand shaped." Most likely, some early mechanic noticed that the pipe collections that run in and out of the cylinders strongly resembled a pair of hands grasping the cylinder block on either side. All internal combustion engines have two manifolds: the intake, or inlet and the exhaust, or header. The intake manifold is usually made from aluminum.

Its purpose is to provide a passage for the gas-fuel mixture to enter the cylinders. A header (exhaust manifold) collects exhaust gases from the cylinders and deliver them to the exhaust system via the catalytic converter.

Because the exhaust gases are very hot, headers are typically made of cast iron. There are two types of headers. A collector style header is the most common. It uses pipes that merge into a collector. The "zoomie" header has no collector, and is found mainly on high performance racing machines. The stock Cadillac Escalade header is of the "collector" type. Headers have long been a common after market item, and some auto manufacturers actually use these as original equipment.
