These 4 Signs Could Indicate Exhaust Failure
Nobody likes it when their vehicle is making unusual sounds. If you hear a few common signs, then it might mean that you have an exhaust leak, which can be loud. Four signs of an exhaust leak include: popping, hissing, vibration, and reduced gas mileage.

When the engine is on, if you hear a hissing or popping sound, you might have a problem with your exhaust system. A vibration in the vehicle can also signal rusty exhaust components, especially if the condensation isn't evaporating due to short drives.
