Milltek Non-Resonated OPF/GPF Back System - Land Rover Defender 110 P300 & P400e - Polished Tips - SSXLR135

The loud one. This Milltek OPF/GPF back system suits the Land Rover Defender 110 with the 2.0 I4 P300 or the P400e plug-in hybrid, 2020 to 2026, and replaces the exhaust from the particulate filter back. The filter itself is retained. The OE rear section is heavily silenced by design, and taking it out is what lets the four cylinder be heard at all. Everything hangs on the factory mounting points for a direct OEM fit, with no cutting and no welding needed, and both OPF/GPF and non-OPF/GPF equipped vehicles are covered.

The system is hand-finished T304L stainless, mandrel bent for a clean full-bore path and CNC-formed at the junctions, using the standard hanger locations. The exits are four polished GT-90 style trims, mirror finished so they catch light against the rear valance. What sets this version apart is the MSRR88REP delete pipe in place of the front silencer. That is a straight-through section, not a muffler, and it is the reason this build is loud: bigger volume everywhere, a hard aggressive edge under load, and yes, some resonance at steady motorway speeds. If a quiet cruise matters more to you, buy the resonated version instead. This one is for people who want to hear it.
