5 Signs of an Exhaust Leak

As your engine runs, the exhaust gases and noise from combustion are routed through an exhaust system. The exhaust system safely routes toxic gas to the rear of the vehicle, away from the passengers and driver. It also muffles the noise of your engine operating and helps control emissions through the use of catalytic converters. The exhaust system is an essential component of your vehicle.

However, on most vehicles, the exhaust system runs underneath the car and is exposed to harsh driving conditions, road salt, and debris, and extreme temperatures. Rust, damage, and worn-out gaskets can all lead to an exhaust leak, and exhaust leaks can impact your vehicle’s performance, emissions, and even your health.

Here are 5 indicators you have an exhaust leak.

1.)   Loud Operation

If you have an exhaust leak, one of the most noticeable symptoms is noise. If the leak occurs before the muffler or on the muffler itself, you may notice more noise than you are used to. Depending on the cause of the leak, your car may get louder and louder as time goes on.

2.)   Loss of Power 

An engine runs optimally when exhaust flow is uninterrupted. An exhaust leak causes a drop in back pressure, which can lead to a decrease in power and sluggish acceleration. A loss of power can be attributed to many potential issues. If you notice a loss of power in addition to some of the other symptoms on this list, an exhaust leak may be to blame.

3.)   Poor Fuel Economy

The fueling system in your vehicle uses oxygen sensors to determine whether your car is running rich (too much fuel), lean (not enough fuel), or stoichiometric (correct balance of air and fuel). The oxygen sensors are located in the exhaust system. A leak before an oxygen sensor can make it appear as if the car is running lean. As a result, the engine computer will request more fuel to correct the lean condition, reducing fuel economy.

4.)   Exhaust Odor While Driving

If you have an exhaust leak, you may notice the smell of exhaust fumes while you drive. This can be a major safety hazard. Inhaling the noxious fumes can lead to carbon monoxide poisoning. If can smell exhaust fumes while you drive, roll down your windows and get your car to a shop as soon as possible.

5.)   Vibration

As fumes escape from leaks in the exhaust, noticeable vibrations can be felt while your car is on. The vibrations may become more severe when you step on the gas and the rate of airflow through the exhaust system increases.
