Milltek Sport Active Valve Control for Land Rover Defender 5.0 V8
The Milltek Sport SSXLR160 is a plug and play valve control module designed specifically for the Land Rover Defender 5.0 V8. It gives you full manual control over the exhaust valves, letting you switch instantly between a quiet, refined drive and the full roar of the supercharged V8 – all at the press of a button.
One of the best features of this controller is its flexibility. It works seamlessly with the factory OE exhaust system as well as any compatible Milltek Sport exhaust, so you can enjoy on demand sound control whether or not you’ve upgraded the rest of your exhaust setup.
How It Works
The module connects directly into the vehicle’s existing valve control wiring, requiring no permanent modification or cutting of the OE loom. Two remote key fobs are supplied, allowing you to switch between three driving modes on the fly:
- Open 100% – valves held fully open for maximum exhaust note and a more aggressive sound
- Closed 100% – valves held closed for the quietest, most refined driving experience
- OE Mode – returns full control to the vehicle, using the factory drive select modes and RPM ranges to operate the valves automatically
A built in memory function remembers your last selected mode, so the Defender will start up exactly how you left it. No need to reset your preference every time you get behind the wheel.
Why Fit a Valve Controller?
From the factory, the Defender V8’s active exhaust valves are governed by the vehicle’s drive mode and engine RPM. That means the loudest setting is only available in specific conditions, and the quietest mode isn’t always selectable when you want it. The Milltek controller removes those restrictions, putting the sound character of your V8 entirely in your hands. Whether you’re leaving home early in the morning, cruising through town, or enjoying a spirited drive on an open road, you can tailor the exhaust note to match the moment.
Fitment
This valve controller is designed for the Land Rover Defender 5.0 V8 models. Please use the site’s vehicle lookup tool or check the Vehicle Fitment tab to confirm compatibility with your specific vehicle before ordering.
Installation typically takes around 1 hour, including removal and refitting of any relevant components. As it’s a true plug and play unit, no specialist tools or coding are required.
