cars in city with lots of exhaust

Do you have a noisy vehicle? If so, you may need a new muffler or exhaust system from our team here at Harold's Used Auto Parts Inc in Philadelphia. The purpose of your exhaust system is not only to reduce the noise but also to redirect fumes away from your vehicle. Redirecting these fumes protects passengers in the car from toxins created by burning fuel.

Carbon monoxide is a colorless, odorless chemical that can escape from an unsecured exhaust system, and if inhaled can pose very serious health hazards. If you experience an unusually loud sound coming from your vehicle, it is vital to get your exhaust system checked immediately!

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.
