Symptoms of a Bad or Failing Exhaust System Hanger

The exhaust system hangers, also known as exhaust supports, are the mounts that are used to secure and support the exhaust pipes to the underside of the vehicle. The exhaust hangers are usually made of rubber to absorb vibrations from the engine and to allow for flex for the exhaust to move as the vehicle travels. They play a key role in properly securing the exhaust and preventing noise and vibration in the cabin. When one or more of the exhaust system hangers has an issue, it can cause problems with the exhaust system and can compromise cabin comfort. Usually bad or failing exhaust hangers will produce a few symptoms that can alert the vehicle of a potential issue.

1. Exhaust hangs visibly low

One of the first symptoms of a problem with an exhaust hanger is an exhaust that hangs lower than normal. The exhaust system hangers are made of rubber, which can dry out, crack, and break over time. If an exhaust hanger breaks, it can cause the vehicle’s exhaust pipes to hang visibly low, underneath the vehicle, from lack of support.

2. Excessively loud exhaust making hissing sounds

Another symptom of a problem of a possible problem with an exhaust hanger is an excessively loud exhaust. If any of the exhaust pipes break or crack from lack of support, an exhaust leak can be produced. The vehicle may produce a hissing or tapping sound from underneath the vehicle that may be more pronounced when the engine is cold and during acceleration.

3. Decrease in power, acceleration, and fuel efficiency

Another symptom of a possible problem from exhaust hangers are engine performance issues. If any of the exhaust hangers break or fail, they can place additional stress on the vehicle’s exhaust pipes, which can cause them to break or crack. Broken or cracked exhaust pipes will create an exhaust leak, which if large enough, will not only produce excessive noise, but will also cause a reduction in power, acceleration, and even fuel efficiency.

Exhaust system hangers are a simple component, however, they play an important role in securing and dampening the vibrations of the vehicle’s exhaust system. If you suspect that one or more of your vehicle’s exhaust hangers may be having an issue, have the vehicle inspected by a professional technician, such as one from YourMechanic, to determine if your vehicle needs an exhaust hanger replacement.
