A loud exhaust sound can be a warning sign that your vehicle’s exhaust system is malfunctioning. Usually, this problem is caused by a faulty exhaust manifold. When this happens, you’ll hear hissing or tapping noises. This indicates that the exhaust manifold seal is broken and carbon dioxide is slowly leaking into your vehicle. This problem is particularly noticeable on cold mornings.

Loud exhaust can also be caused by a leaking muffler. This can cause the engine to run louder than usual, and can make your passengers feel the vibration. The loud noises will continue until you turn off your vehicle. If you’re driving at speed, you’ll probably hear spitting and popping noises coming from the exhaust.

The loud sound can also be caused by a number of other problems, including a damaged muffler. The exhaust may have been rusted or it could have a loose manifold. A corroded catalytic converter can also cause a loud exhaust sound.
