Automotive Q&A

Answer:

Determining how long your exhaust system will last is very difficult. There are many factors such as climate and driving conditions (dusty areas) that can affect the life of your exhaust system. Typically, a normal exhaust system will last anywhere from two to three years. However, it is important to check your exhaust system periodically for any damage.

There are several things to look for to determine if you should have your exhaust system inspected or to have any part replaced. If you don’t accelerate or drive any faster when you step on your gas pedal, your catalytic converter may be clogged. You will also experience a noticeable drop in gas mileage and possible stalling. However, if your converter is completely clogged, your engine will quickly fail because of all of the exhaust backpressure. Also, if your engine’s oxygen sensor or any part of your exhaust system fails, your “check engine” light will come on. If the “check engine” light comes on and stays on, you should have your vehicle checked immediately.
