Milltek non-resonated OPF back exhaust system for Land Rover Defender 90 3.0 I6 P400 (2020+). Direct factory fitment using OEM hangers and mounting points - no modification required. Cat-back design begins after the original particulate filter, preserving emissions compliance while unlocking full throttle character.
