Hi Rachel, there are a few common issues with the BMW 3 Series exhaust system that you may be experiencing. One of the most common issues is a leak in the exhaust manifold. This can cause strange noises and a decrease in performance. Another issue could be a clogged catalytic converter, which can also lead to decrease in performance. I would recommend taking your car to a trusted mechanic to diagnose and fix the issue as soon as possible.

Hey Rachel, I've had some experience with similar issues in my 3 Series. In my case, the problem was a faulty oxygen sensor. This can cause the check engine light to come on and affect the exhaust system's performance. I would suggest getting the sensor replaced and keeping up with regular maintenance to avoid any further issues. Hope this helps!
