Milltek’s V8 Exhaust Wakes Up the Defender OCTA — Hear the Beast Roar!

Milltek has officially begun production of its performance exhaust system tailored for the Land Rover Defender OCTA equipped with the twin-turbocharged eight-cylinder engine. Designed to elevate the driving experience, this new system adds the deep, rich sound that many feel the powerful 635 horsepower engine truly deserves.

The system had its public premiere at the Goodwood Festival of Speed earlier this July, where it was showcased on a specially prepared Defender OCTA. The design features a gas particulate filter-back configuration and includes a non-resonated twin 80 millimeter layout. This setup keeps the original valve control mechanism intact, so you still get that dynamic exhaust sound while staying compliant with current emissions regulations.

Milltek is offering a few custom options to help owners make the Defender OCTA more personal. Enthusiasts can choose GT100 tailpipe tips in polished black, brushed titanium, or burnt titanium. For those who prefer a more subtle look, there is also the option to retain the original factory-style outer tips.

What makes this system especially well-suited for off-road adventures and long road trips is its construction. The exhaust is built using T304L grade stainless steel, a durable and corrosion-resistant material that is ideal for vehicles that get used hard and often.

For drivers who want a more aggressive tone from their Defender OCTA, this system delivers a noticeably deeper and more powerful sound. And thanks to the retained valve control, the system provides both volume and refinement depending on your driving mode or throttle input.

If you are curious to hear the difference, there is a side-by-side comparison available that highlights the before and after exhaust note. It is clear that Milltek has engineered something that adds to the soul of the Defender OCTA without going overboard.

This launch is a big moment for fans of high-performance sport utility vehicles. Milltek’s exhaust gives the Defender OCTA not only a voice to match its performance but also a level of craftsmanship that complements Land Rover’s boldest and most powerful model to date.
