Ford's exhaust manifold, like any other exhaust manifold is part of the exhaust system that works collectively to keep the exhaust gases in one direction, silence the engine noise produced by engine combustion, convert these gases into lesser harmful ones, and save fuel.

The exhaust manifold is the first pipe among the series of pipes and tubes that can be located at the system. It is attached at the engine particularly the engine cylinder to scoop the exhaust gases. Usually made from cast or nodular iron, the exhaust manifold is a contraption that is designed depending on the type of the engine employed in the vehicle and the number of cylinders the engine has. In other words, the number of exhaust manifolds depends on how many cylinders are present. Without the exhaust manifold there will be no connection between the exhaust system and the engine.

After the gases exited the cylinder and passed through the manifold, it will directly go to the catalytic converter which will convert the hydrocarbons or the unburned fuel, carbon dioxide, sulfur dioxide, carbon monoxide, nitrogen oxides, phosphorus lead and other metals into lesser gases like water vapor and carbon monoxide.

There are several other parts in the exhaust system wherein these gases would pass before it reaches the air outside: the oxygen sensor that measures the oxygen content of the exhaust that could help the fuel economy of the vehicle, the muffler and the resonator that significantly reduce the noise of the engine, the exhaust pipe that connects all the parts of the exhaust system together, and the tail pipe that enables the gases to exit the vehicle system. The exhaust system significantly reduces the pollution caused by fuel combustion on car engines.
