If you're concerned that the exhaust system of your vehicle is malfunctioning, you might want to learn a little about the most important exhaust system components.

There are several components of the exhaust system that could possibly be the cause of exhaust system malfunctions. You'll want to know what part is causing your malfunction and approximately how much it costs to replace when you need car exhaust repair. The following are five main exhaust system components that frequently need to be repaired or replaced. 

The exhaust manifold

An exhaust system's exhaust manifold attaches to the engine block and filters toxic gases produced during combustion into the exhaust pipes. If there is a malfunction with the exhaust manifold, these toxic gases could get trapped in the engine. This could create a situation where the engine becomes damaged. This makes it very important to repair a malfunctioning exhaust manifold quickly.

The oxygen sensor

A vehicle's engine needs oxygen for combustion to occur. The oxygen sensor in a vehicle is an exhaust system component that helps ensure that the right mixture of fuel and oxygen reaches the engine for efficient combustion. A vehicle with a malfunctioning oxygen sensor will lose fuel efficiency. Fortunately, an oxygen sensor replacement is not generally that expensive.

The muffler

The primary function of the muffler is to silence the noise that is produced during combustion by the engine. A malfunctioning muffler is usually pretty obvious because it will cause a vehicle to make a great deal of noise while it is running. The muffler doesn't only manage noise production. It also helps to get rid of toxic gases produced during combustion. A muffler that is functioning properly is not only important for a comfortable vehicle ride but also to meet inspection requirements. You can fail a vehicle inspection if your muffler is malfunctioning.

The catalytic converter

A vehicle's catalytic converter is responsible for converting gases given off during combustion like carbon monoxide into carbon dioxide and water vapor. Catalytic converters are required on vehicles for the sake of the environment. While your vehicle may still be able to run with a malfunctioning catalytic converter, it will probably not be able to pass inspection. Also, a malfunctioning catalytic converter sometimes gives off an unpleasant smell similar to rotten eggs. 

The tailpipe

The tailpipe channels exhaust gases out behind the vehicle. Over time, the tailpipe can become damaged by corrosion or impact damage.
