BMW made two versions of the factory downpipe for the new F Series N55 Engine. The early version ran from build date 2012 to 08/2013. The second version ran from build date 09/2013 and on. The build date of your car can be found on a stick on the driver's side door jam. These downpipes are not interchangeable. Make sure you order the correct downpipe for your car.
