The Exhaust Manifold is a part of your vehicle's exhaust system. Its primary function is to collect the exhaust fumes from the engine cylinders and direct them to the exhaust pipe. They are constructed from steel, cast-iron or heavy gauge steel. In addition to collecting the exhaust gases, the exhaust manifold also helps in keeping the heat, gases and air from leaking out. As the exhaust manifold minimizes heat loss, it consequently prevents the engine and other heat-sensitive parts from overheating. Since it collects the gases from different cylinders, a back-pressure develops inside the manifold.
This back pressure is removed through the exhaust header. The exhaust header allows for each engine cylinder to have its own exhaust pipe. The exhaust pipes have the same length. All of these pipes join together into a single pipe called the collector. Since the exhaust pipes are of the same length, it ensures that the exhaust gases are spaced out evenly when they reach the collector and thus eliminates any back-pressure in the exhaust.
If your exhaust manifold is damaged, you might hear a clicking, whistling or sputtering noise when you start your engine. A cracked manifold can also cause a vacuum leak, which could result in a lowered efficiency of your engine. If your car's exhaust manifold is cracked or damaged, you should replace it at the earliest. At Buy Auto Parts we stock a wide variety of exhaust manifolds for every car make and model.
