The Land Rover Defender OCTA and Ineos Grenadier just got a serious upgrade, and Milltek is behind the transformation. At this year’s Goodwood Festival of Speed, Milltek is showcasing its latest performance exhausts and rugged design accessories, and the spotlight is firmly on the Land Rover Defender OCTA.
Milltek’s engineers didn’t just tweak, they reimagined. The Land Rover Defender OCTA now features a bespoke GPF-back twin 80mm non-resonated performance exhaust system. It enhances the sound of the 635hp V8 engine without affecting emissions. The result? A deeper, more aggressive tone that matches the OCTA’s muscular presence.
Power and Sound: Defender OCTA’s V8 Comes Alive
The Defender OCTA’s twin-turbo V8 already delivers a mighty 635 horsepower. Milltek’s new exhaust system takes that power and gives it a voice. With twin valves and a reflective rear silencer, the system preserves valve control while eliminating the center resonator for a rawer sound.
Owners can choose from GT100 exhaust tips in polished black, brushed titanium, or burnt titanium. Or, for a more understated look, the original tips can stay. Either way, the sound is unmistakable, deep, bold, and built for enthusiasts.
Milltek Design Accessories Add Rugged Style
Milltek didn’t stop at sound. The Defender OCTA on display at Goodwood wears a full suite of Milltek Design accessories. Prototype side steps, a rear spoiler, and rear storage boxes give it a more aggressive stance and added utility. A Milltek spare wheel cover completes the look.
These parts aren’t just for show. Built from high-quality steel, they’re engineered for durability and real-world use. Whether you’re tackling trails or turning heads in town, they’re made to last.
Ineos Grenadier Gets the Full Milltek Treatment
The Ineos Grenadier also gets a performance boost with a particulate-back non-resonated exhaust system. Its 280+ hp six-cylinder engine now sounds more purposeful, thanks to Milltek’s tuning expertise.
But it’s the accessories that really set this Grenadier apart. A 24-piece replacement front bumper, new grille, roof light bar, and side steps give it a commanding presence. Underneath, protective gear like engine and transmission guards and a transfer box guard ensure it’s ready for serious off-road action.
Built for Performance, Designed to Endure
Milltek’s reputation was forged in grassroots motorsport, and that DNA runs through every product. From CAD modeling to CNC tooling, each part is crafted with precision. The use of T304L stainless steel ensures long-term durability, even in the harshest conditions.
These aren’t mass-produced accessories, they’re purpose-built enhancements for drivers who demand more from their vehicles.
A Festival of Performance
Milltek’s stand at Goodwood isn’t just about off-roaders. Performance fans can also check out new exhaust systems for the BMW M5 G90 and Porsche 992.2 Carrera hybrid. And for those looking to take a piece of Milltek home, merchandise like hats, hoodies, and wall art will be available all weekend.
Summary
Milltek’s debut of the Land Rover Defender OCTA and Ineos Grenadier at Goodwood is a celebration of sound, style, and engineering. With performance exhausts and rugged accessories, these off-roaders are ready for anything, from the trail to the tarmac.
