Purpose: Exhaust pipes route exhaust gas away from the engine, through the catalytic converter and muffler and out the rear of the vehicle. As a result, pollution and sound are reduced, while ensuring safety by directing exhaust gas away from the vehicle.
Maintenance Tips/Suggestions: Have your vehicle's exhaust system inspected periodically to keep your car safe. Exhaust pipes may not be individually replaceable due to the condition of other exhaust system components, or because the original exhaust system uses a unitized construction, where sections are welded together. Keep in mind that exhaust gas, especially carbon monoxide, can be deadly if it enters the interior of the car. The symptoms of an exhaust leak may include a louder than normal exhaust sound, the sound of exhaust coming from unusual places on your car, a ticking noise when accelerating, and the smell of exhaust. However, don't rely on your sense of smell as a conclusive means of determining if there is an exhaust leak. Carbon monoxide has no odor. If you suspect any problem with the exhaust system, have it inspected immediately by a professional technician. Another symptom of a potential exhaust leak is a failed emissions test. A leak not only lets exhaust gas out, it also allows oxygen to enter the exhaust stream, which can be detected during an emissions test. You will usually be required to make repairs before retesting, so have the leak checked by a professional technician.
