Answer: Technicians recommend that you have your entire exhaust system inspected every two to three years, but there are several things you can look for to determine if you should have your center exhaust section inspected. 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 catalytic converter is completely clogged, your engine will quickly fail because of all the exhaust backpressure. A damaged muffler is fairly easy to notice; your vehicle will be much louder when driving. If you ever smell any emissions coming from your vehicle, you may have a damaged exhaust pipe causing the emissions to leak. Lastly, if your “check engine” light comes on and stays on, it is possible that your exhaust system is damaged or leaking. No matter what, it is crucial to inspect your center exhaust section periodically to check for any damage and to ensure safe driving conditions.
