The exhaust manifold, also known as the exhaust system header, is made up of metal pipes bolted to the exhaust side of the engine. However, the inner manifold is separate from the header manifold.
Most exhaust system manifolds are made of iron and steel.
A gasket between the manifold and the car’s engine helps to seal the gas between the engine components. Even though manifolds have different designs, the primary purpose of each manifold is the same: channelling the fumes in the pipes to run down the car’s length.
Only a few cars' exhaust systems have downpipes, which connect the manifold to the catalytic converter. In most cars, the cats are integral to downpipes. However, in a few vehicles, the downpipes are integral to pre-cats.
The exhaust system downpipe is known for features such as the “Flexi” section. Its primary purpose is to let the engine run without any risk of vibration or unusual movement in the engine’s components.
We all know that a car’s engine emits chemicals and fumes that are not good for the atmosphere. The primary purpose of the catalytic converter is to convert the fumes and chemicals into less toxic emissions.
A catalytic converter also converts carbon monoxide into carbon dioxide. This conversion results in less harmful fumes and chemicals. However, these fumes are still not completely harmless.
A lambda or oxygen sensor is also mounted on the catalytic converter pipe. This sensor monitors the gas entering the pipe and ensures it works correctly. If the gas entering the pipe is not working appropriately, an oxygen sensor will turn on a warning light on the car’s dashboard.
The last and one of the most essential exhaust system parts is the car muffler. Mufflers in automobiles are fitted near the exhaust system’s pipe end. The basic purpose of an exhaust muffler is to muffle the sound that occurs due to engine explosions to save the environment from noise pollution and comply with noise pollution legislation.
