*Note that while the Stage 3 OTS Maps are available, there is not a Stage 3 Power Package for the 2020 Mustangs equipped with active exhaust (this includes all HPP cars and non-HPP active exhaust cars).  This is due to the lack of compatibility of the COBB Cat-back exhaust with the active exhaust valve on these vehicles.
