2020-2023 Explorer non-hybrid vehicles equipped with a 3.0L EcoBoost or 3.3L Duratec engine and 2020-2023 Aviator non-hybrid vehicles equipped with a 3.0L EcoBoost engine may exhibit an exhaust rattle requiring replacement of the left or right exhaust flexible pipe (5G203). The updated part locates the flexible joint portion of the pipe closer toward the catalytic converter than the originally equipped part. This is due to a design change with these replacement components which will not cause any functional issues with the vehicle.
