Figured I would ask to see if anyone would be able to help me. I have a 100% stock 2014 wrx with only 2850 miles. Out of the blue the left side of the exhaust starts rattling and eventually stops. It happens randomly. It's quite noticeable if you're near the rear of the car. If you hold onto the tip of the exhaust it does stop as well. I could understand if I had a cat back or messed with the exhaust at all but its all stock and untouched. So if anyone has any suggestions they would be appreciated. Thank you for your time.
