Milltek OPF/GPF back system for the Land Rover Defender 110 running the 2.0 I4 P300 or the P400e plug-in hybrid, 2020 and later. An OPF/GPF back system replaces the exhaust from the particulate filter rearward, leaving the filter itself in place. It is the section that matters for sound: the OE rear silencing is tuned for showroom quiet, and lifting that restriction lets the engine note carry through instead of being smothered. The system bolts to the OEM mounting points with no cutting and no welding, and fits both OPF/GPF and non-OPF/GPF equipped vehicles.
Underneath, the system is hand-finished T304L stainless with mandrel-bent piping and CNC-formed junctions, located on the factory hanger points. The visible difference is at the back: four JET-90 style tips in woven carbon fibre, with stainless inner sleeves and a lacquered weave that stays sharp against heat and road grime. The carbon picks up the Defender's black exterior pack without shouting about it. Acoustically this is the resonated configuration, with the MSRR88 front silencer retained, so the car stays civil and drone-free at cruise and only gets vocal when you load the engine up.
