What is an Exhaust Manifold?

An exhaust manifold is a system which is used to vent exhaust gases away from an engine. The manifold extends from the cylinders to the exhaust pipe, collecting and moving exhaust away from the engine. Exhaust can be harmful to inhale, making it very important to have a fully functional exhaust manifold; because it can sometimes be difficult to detect an exhaust leak, people may inhale exhaust gases without being aware of it.

When the pistons in the engine reach the exhaust stroke, they push the exhaust fumes up into the exhaust manifold. The manifold consists of a series of pipes which connect to the cylinders and then consolidate in a central large pipe which vents to the exhaust pipe. A series of gaskets are used to create tight seals so that exhaust cannot escape from the cylinders.
