Why is my BMW M3's exhaust making a loud rattling noise?

I have noticed that my car's exhaust is making a loud rattling noise while driving. It only happens when the car is in motion and gets louder as I accelerate. What could be causing this issue and how can I fix it?

It is possible that there is a loose or damaged component in your exhaust system, such as a muffler or exhaust pipe. I would recommend bringing your car to a certified mechanic for a thorough inspection to determine the exact cause of the noise.

Another possible reason for the rattling noise could be a failing exhaust hanger. These are responsible for holding the exhaust system in place and can wear out over time. It is a relatively easy fix to replace the hanger, but I would still suggest having a professional handle it to ensure proper installation.
