Do you have an aftermarket exhaust or have you had a remap?  Could be the connecting pipe has moved between the down pipe to rear section of the exhaust.
I had the same recently, due to engine torque, it had pushed my milltek exhaust tips to stick further out at the rear of the car when warm.Caused an idle rattle under the car because the exhaust on the rubber hangers had pushed been pushed right back!

Long shot but cured mine
