The exhaust manifold is a set of pipes, one for each cylinder in the car, that takes the burned exhaust gases from the cylinders and ejects them through the exhaust system, through the car's tail pipe and into the outside air. The exhaust gases are the burned fuel/air residue from the cylinders in the engine. These gases must be vented out of the car, because many of them, like carbon monoxide, are toxic and can cause injury or death if inhaled. Sometimes pollution control mechanisms like catalytic converters are used in the exhaust system. Mufflers are also used to dampen the sound of the exhaust gases escaping.
