Most drivers tend to take their vehicle’s exhaust system for granted until something goes wrong. However, this car part is responsible for pushing gases and exhaust fumes away from the vehicle while shielding passengers from the noises made during the fuel-burning process. Here’s a brief explanation of the various components within the exhaust system as well as some common problems attributed to this car part.

4 Elements of an Auto Exhaust System

1. Exhaust Manifold

This car part is attached to the engine’s cylinder head. It’s used to channel gases from various cylinders into a single pipe for expulsion through the muffler, and it also burns remaining fuel left in the engine. If the engine begins making excessive noise, your exhaust manifold may be faulty.

2. Muffler

At the end of the exhaust system is the silencer, which is used to reduce combustion noises from the engine chamber. Since it has to withstand extreme heat and corrosive chemicals within burned fuel, this car part is typically made of steel that’s coated with aluminum. A noisy exhaust is usually a sign of a leak in the muffler.

3. Oxygen Sensor

This component is located near the manifold, and it measures the oxygen inside the exhaust system. The oxygen sensor will make adjustments to the amount of fuel that reaches the engine based on how hard the accelerator pedal is pressed and how much fuel the car needs to reach the desired speed. If this component is malfunctioning, it can produce foul odors, increase exhaust emissions, or damage other parts of the system, like the catalytic converter.

4. Catalytic Converter

As one of the most critical parts within this system, the catalytic converter turns dangerous carbon monoxide and hydrocarbon gases into nonhazardous water vapor and carbon dioxide. This part can develop clogs from chemical deposits, which can leave behind the smell of rotten eggs or sulfur.
