Milltek Resonated OPF/GPF Back System - Land Rover Defender 110 P300 & P400e - Cerakote Black Tips - SSXLR131

This is the Milltek OPF/GPF back system for the Land Rover Defender 110 running the 2.0 I4 P300 or the P400e plug-in hybrid, 2020 to 2026. An OPF/GPF back system starts immediately behind the particulate filter and replaces the OE rear section only. The filter is retained. Because the particulate filter and the restrictive factory silencing behind it flatten the exhaust note between them, changing the section you are allowed to change is what brings the tone back. Everything mounts to the standard hanger points, so there is no cutting and no welding, and both OPF/GPF and non-OPF/GPF cars are covered.

Construction is hand-finished T304L stainless, mandrel bent so the bore never pinches, with CNC-formed junctions carrying flow out to the four exits. The tips are GT-90 style trims in Cerakote Black, a hard ceramic coating chosen because it holds its colour under exhaust heat instead of fading to grey the way cheap black finishes do. Against a Santorini Black or Gondwana Stone Defender the effect is deliberately understated. The acoustics match that: with the MSRR88 front silencer retained, the cruise stays quiet and drone-free, and the character arrives only when you ask for it at load.

• Material: hand-finished T304L stainless steel throughout
• Acoustic configuration: resonated, front silencer retained for a settled motorway cruise

• Pipe diameter: 3.00" (76.20mm), mandrel bent
