I then started the car without the tips again and listened closely, the rattle came from the right side or passenger side of the exhaust. I thought it was a hanger but turns out it's the exhaust valve. I did some research and found that it's the metal wire pin that connects the motor and the actual valve together. Apparently this is a common bmw issue. I plan to solve it this weekend by removing the exhaust and replacing the pin. I will update when I'm finished.
