city of drivers with smog

While your exhaust system helps reduce noise output from your vehicle, it also significantly reduces harmful emissions from being released into the air. When your muffler and exhaust system are functioning properly, it significantly reduces your vehicle's harmful impact on the environment. It also significantly improves the functionality of your vehicle and improve fuel mileage for your car, truck, SUV or Jeep.

An exhaust system is made up of numerous parts that work together to rid your car of the exhaust gases that are created during the combustion cycle, as your engine burns fuel. Each part of your exhaust system has an important role to play in removing exhaust gases away from the engine as quickly as possible, allowing another cycle of combustion to begin. The more quickly and efficiently an exhaust system does this the more efficiently an engine can run. The main parts of an exhaust system are an exhaust manifold, catalytic converter, oxygen sensors, exhaust pipes, and the muffler.

The exhaust manifolds right behind the engine collect exhaust gases and connect to cylinder heads. Gases collected by your vehicle's exhaust manifolds are analyzed by oxygen sensors and refined by catalytic converters before being muffled by the mufflers. By the time these gases reach the muffler, the emissions system has made your car run smoother, quieter and cleaner which is more efficient and equals better fuel mileage.

If any of the components of your vehicle's exhaust system fail, your gas mileage and quality of air around you can be affected.
