Description: Exhaust pipe is a general term for several different pipes used throughout the exhaust system. Although configurations vary with different makes, models and engines, there is usually a front exhaust pipe connecting the exhaust manifold to the catalytic converter, an intermediate exhaust pipe connecting the catalytic converter to the muffler, and a tailpipe connected to the outlet of the muffler and serving as the exhaust outlet. Exhaust pipes may be made of standard or stainless steel.
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’s 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.
