Overview

This Milltek Sport cat-back exhaust fits the 2021-2026 Land Rover Defender 90 with the 3.0L P400 six. For the Defender 90 P400, Milltek offers a non-resonated and a resonated system, each with GT-90 round tips in four finishes or carbon fiber JET-90 trims. Each system is built for this exact chassis, so it follows the factory routing, hangs from the stock mounts and keeps the ground clearance of the original exhaust. Compared with the factory steel parts it is lighter, flows more freely and gives the engine a clearer, stronger voice under load, without the harsh highway drone of a cheap straight pipe. The Defender 90 P400 parts are T304L stainless steel with mandrel-bent tubing, which keeps the pipe at full size through each bend and resists corrosion for years. It bolts on with the factory hangers and clamps, with no cutting or welding needed. It replaces the factory exhaust from behind the catalytic converters (and particulate filter, where fitted) back, using 76.2 mm (3 in) T304L stainless steel pipework, and bolts to the factory mounting points.

How to Choose

Start with the Sound. Non-Resonated (Louder) drops the rear resonator for a louder, sportier note. Resonated (Quieter) keeps a resonator for a deeper tone with less drone on the highway.

Then pick an Exhaust Tip Finish: Polished GT-90 (bright polished stainless), Cerakote Black GT-90 (a black Cerakote ceramic coating), Carbon Fiber JET-90 (carbon fiber outer sleeves), Brushed Titanium GT-90 (a brushed titanium finish), Burnt Titanium GT-90 (a heat-blued burnt titanium finish). The finish changes the look only, not the sound.

Fitment Notes

  • Fits the 2021-2026 US-market Land Rover Defender 90 with the 3.0 liter P400 mild-hybrid six. Not for the P300 four or the V8, which have their own pages.
  • Milltek builds these from behind the factory catalytic converters (and particulate filter, where fitted) back, so they work on US cars with or without a filter. Milltek does not list them as race products.
