"Manifold" is from a Latin root that means "hand shaped." Automotive manifold do resemble a pair of hands cradling the engine block "fingers" that feed into or exit from the cylinders. The Ford F250 engine, like those of most vehicles, has two manifolds: the intake, or inlet and exhaust, or header. Unlike the aluminum intake manifold, the Ford F250 Header (exhaust manifold) is made from cast iron that can stand up to the heat of exhaust from the cylinders.
Its function is to collect these exhaust gases and send them on to the exhaust system. Headers come in two varieties: the common collector style header, which uses pipes merging into the collector, and the "zoomie" header, which lacks a collector.
The stock Ford F250 Header is a collector type, while the latter is used primarily for racing vehicles (and not even legal for street vehicles). Headers from after market sources have been around for a long time - many auto manufacturers have begun using these as original equipment.
Today's Ford F250, unlike it's low-powered ancestor (the 90 HP Ford Bonus), is a horsepower monster.
