Milltek Resonated OPF/GPF Back System - Land Rover Defender 110 P300 & P400e - Polished Tips - SSXLR130

A Milltek OPF/GPF back exhaust system for the Land Rover Defender 110 fitted with the 2.0 I4 P300 or the P400e plug-in hybrid powertrain, 2020 to 2026. The system replaces everything behind the particulate filter, so the filter itself stays exactly where Land Rover put it. That is the point: the OE rear section is where most of the character gets absorbed, and swapping it out gives the four cylinder back the tone the filter takes away. Fitment is direct to the OEM hanger and mount positions, with no cutting and no welding required, and the system suits both OPF/GPF and non-OPF/GPF equipped vehicles.

Built from hand-finished T304L stainless steel, with mandrel-bent piping that holds full bore through every curve and CNC-formed junctions where the flow splits to the quad exits. It hangs on the factory rubbers, so ride height and clearance are unchanged. The tips are polished GT-90 style trims, mirror finished and set in a quad layout that reads as a deliberate upgrade rather than a bolt-on. Acoustically this is the resonated build: the MSRR88 front silencer stays in place, which keeps the cabin clean and drone-free at motorway cruise while letting the engine speak with real purpose from half throttle upward.

• Material: hand-finished T304L stainless steel throughout
• Acoustic configuration: resonated, front silencer retained for a drone-free cruise
• Tips: four polished GT-90 style trims
• Pipe diameter: 3.00" (76.20mm), mandrel bent
• Fitting time: 1.5 to 2.5 hours, including removal of the OE system

Nothing here is a catalogue part with a new label on it. Built for the Emotion.
