How many miles did you put on the exhaust? There is a break-in period for the Borla system.

OP check what Harold said, I had this same issue and once fixed the drone is bearable and the trim pieces in the car stopped rattling. and I drive an auto

Tks Bluelion. I don't quite understand the second part of what Harold say. What does "pre-load the system with spin jack" exactly mean? I assuming this would solve the vibrating noise which sounds like something is vibrating? Tks again.
