Milltek Filter-back Exhaust for Land Rover/Range Rover Defender 90 5.0 V8 425PS & 525PS (NAS Non-OPF/GPF Vehicles Only) (2021 onwards) – Sharper Sound, Filter Retained
This is Milltek's particulate filter-back system for the Land Rover/Range Rover Defender 90 5.0 V8 425PS & 525PS (OPF/GPF Vehicles Only). It replaces everything downstream of the factory diesel or petrol particulate filter with wider-bore pipework and re-tuned silencers, cutting back pressure and sharpening the exhaust note. The filter itself is left exactly where the manufacturer fitted it, so emissions equipment is unaffected. It's offered in non-resonated or resonated EC approved versions and 6 tailpipe finishes, so you can pick the setup that suits how the car's used.
It's the right choice if you want a sportier sound and a genuine, if modest, flow improvement on a filter-equipped car, without going anywhere near the parts of the system that keep it emissions-compliant.

Installation
The fitting time varies by version; see the specification table for the option you choose. We recommend professional fitting on a ramp. Once fitted, check the tailpipe alignment and re-check all clamps after the first few hundred miles.
What's the difference between the resonated and non-resonated versions?
The resonated version adds extra silencing for a quieter, more refined tone. The non-resonated version leaves it out, so it is louder and more aggressive.
Which tailpipe finishes are available?
You can choose from: GT-90 Cerakote Black Special Edition, GT-90 Brushed Titanium, GT-90 Burnt Titanium, GT-90 Cerakote Black, GT-90 Polished, JET-90 Carbon Fibre. The finish is cosmetic and does not change the sound.

Does it fit the Land Rover/Range Rover Defender 110 5.0 V8 425PS & 525PS (NAS Non-OPF/GPF Vehicles Only)?
