The car parts that make up your vehicle's exhaust system carry emissions away from the engine, keep the sounds of combustion quiet and unobtrusive, and ensure a certain level of fuel efficiency. The exhaust system is comprised of an intricate network of pipes and chambers, but there are five main components of all systems. Below, these five crucial car parts—and potential problems associated with each—are described in more detail.

A Guide to Car Exhaust Systems

1. Exhaust Manifold

The exhaust manifold attaches to the cylinder head of the engine. It channels exhaust from several different cylinders into a single pipe. Because of its near-constant exposure to heat and stress, the manifold is prone to cracking and breaking over time, which can produce a rattling sound or a vibrating sensation.

2. Oxygen Sensor

The oxygen sensor is a car part connected to the exhaust manifold. It monitors how much unburned oxygen is in the exhaust as a way of regulating the amount of fuel necessary to run the engine efficiently. A faulty oxygen sensor results in decreased fuel efficiency, jerking movements, poor idling, and difficulty starting the engine.

3. Exhaust Pipes

The pipes route the exhaust from the manifold to the tailpipe, where it exits the vehicle. Corrosion can cause an exhaust pipe to leak, which can make the engine lose power, decrease the vehicle's ability to accelerate effectively, and lessen fuel efficiency.

4. Catalytic Converter

The catalytic converter is one of the most essential car parts, making vehicle emissions safe for drivers, passengers, and the environment. It converts toxic gasses from the exhaust manifold into carbon dioxide and water vapor. Signs of catalytic converter issues include sluggish engine performance, a foul, sulfurous smell, and a reduction in acceleration.

5. Muffler

The natural process performed by a standard combustion engine is a loud one, and the muffler silences much of it, making for a quieter and more pleasant driving experience. The muffler, connected to the tailpipe, absorbs the bulk of the sound coming from the rest of the exhaust system. When there is an issue with a muffler, common red flags include loud noises, less fuel efficiency, or the smell of exhaust fumes in the cabin.
