You can reduce your need for auto repair services when you know more about how your vehicle operates. This includes learning about the various exhaust components and recognizing the signs of trouble. This overview will help you gain a better understanding of this essential system.

4 Components of Your Car Exhaust System

1. Exhaust Manifold

This sits on top of the engine and collects the motor gases. These are sent through the exhaust system until they are released through the tailpipes. If the exhaust manifold is exposed to long-term engine heat, cracks and holes develop.

You can recognize this problem through a resonating or whistling coming from the engine. In that case, the auto repair shop will replace the manifold before the entire exhaust system is damaged.

2. Oxygen Sensor

The oxygen sensor regulates how much fuel is sent to the engine. A failing oxygen sensor will usually trigger the check engine light. Additionally, poorer gas mileage should also prompt you to seek an auto repair technician, who can check out this sensor.

3. Catalytic Converter 

This part of the exhaust system is located midway between the exhaust manifold and muffler. It turns highly toxic gases, including carbon monoxide and hydrocarbons, into carbon dioxide and water.

You’ll need an auto maintenance professional to check your catalytic converter if your vehicle has a difficult time accelerating or maintaining speed. Darker or black smoke released from the exhaust pipes can also be a sign of a bad catalytic converter.

4. Muffler

Constructed from steel and aluminum to ensure it can endure exposure to extreme heat and corrosive chemicals, the muffler is located at the rear of the vehicle. It’s the last component before the exhaust pipes, which are responsible for expelling the remaining gases and moisture.

The muffler silences the entire process of running the engine and regulating exhaust. If your car or truck is making a loud rattling noise, your auto repair technician may need to replace the muffler.
