Classic Signs of a Damaged Exhaust System

While exhaust systems are built to withstand the high stress and heat conditions of your engine’s exhaust, they are still prone to corrosion and rust over time due to the high-stress conditions they are constantly under. Usually, a problem with the exhaust system will be quite obvious. Here are some classic signs of a damaged exhaust system:

1) A Noisy Engine Exhaust

One of the first symptoms of a problem with the exhaust is excessive noise. If the exhaust pipes or manifold break or crack they can cause an exhaust leak which, in turn, causes a noisy engine. This usually sounds like a hissing or tapping, which may become louder during acceleration.

2) A Decrease in Power, Acceleration, and Fuel Efficiency

Performance issues are a common symptom of a problematic exhaust manifold. If the pipes become damaged or corroded, they can sometimes produce an exhaust leak. A leak or crack can cause the vehicle to experience a reduction in power, ability to accelerate, and fuel efficiency due to the loss of backpressure.

3) A Burning Smell From the Engine Bay

Another common symptom of problems with the exhaust manifold is a burning smell from the engine bay. While manifolds are built to be heavy duty parts, able to withstand over nine hundred degrees Fahrenheit if there are any issues with the heat shield or exhaust leaks the excess heat can damage electrical and plastic parts nearby. Burning components can produce a smell, sometimes accompanied by smoke, and can lead to other issues. Any burning smells should be checked out immediately to make sure that there is not a major issue.

4) Smell of Raw Gasoline From the Exhaust

A common symptom of a problem with the exhaust tubes is a noticeable exhaust smell, similar to the smell of raw gas. If any of the exhaust systems pipes or tubes become damaged and leak, the exhaust fumes may find their way into the cabin, giving off a smell of raw gasoline.

5) A Hanging or Dragging Exhaust Pipe

This tends to be an obvious sign. If any of the pipes breaks or cracks, they can sometimes hang or drag underneath the vehicle. The pipes may be visible from the side of the vehicle or scrape on the ground. If this happens, you need to see a mechanic right away.
