Milltek OPF-back exhaust system for Land Rover Defender 110 3.0 I6 P400 (late 2018+). Direct factory fitment using OEM hangers and mounting points-no modification required. This resonated cat-back configuration is engineered to restore the natural tone lost through the gasoline particulate filter while maintaining street legality and emissions compliance.
