Milltek chose the Goodwood Festival of Speed held from July 10 to 13, 2025, to unveil its latest performance exhaust system specifically designed for the Land Rover Defender OCTA’s potent twin‑turbo V8 engine . This gasoline particulate filter‑back twin 80‑mm exhaust enhances the vehicle’s acoustic presence without impacting emissions compliance, as it retains original equipment valve control.
The system offers both visual and auditory upgrades. It features a reflective rear silencer and omits a centre resonator to improve exhaust flow and produce a richer exhaust note. Buyers can choose from optional GT100 tips—available in polished black, brushed titanium, or burnt titanium—while still retaining the original tips for a more understated appearance
Milltek’s presence at Goodwood also highlights its broader portfolio, including exhaust systems for high‑performance hybrid models from BMW and Porsche, plus the Ineos Grenadier. Visitors to Milltek’s stand can explore these products and purchase branded merchandise such as hats, hoodies, and wall art directly onsite
Established in 1983 in the UK, Milltek has grown into a globally respected manufacturer of performance exhausts. With headquarters in Derby, UK, and facilities near Germany’s Nürburgring and in Tennessee, USA, the company develops and tests its products using precision equipment. All systems use T304L grade stainless steel, supporting durability and high manufacturing standards
Kev Hall, Milltek’s Technical Operations Manager, remarked on their Goodwood showcase, stating it marks their twentieth appearance and highlighting the importance of the Defender OCTA project among their recent efforts . This long history at Goodwood demonstrates Milltek’s dedication to performance engineering and its appeal to enthusiasts.
The Defender OCTA, with its 635‑hp twin‑turbo V8, benefits from the new exhaust in terms of cleaner sound delivery and potential performance optimization. The use of OE‑styled valve control ensures compliance with emissions regulations while offering a more aggressive tone.
Milltek’s inclusion of the Ineos Grenadier exhaust kit reinforces its strategy of catering to emerging off‑road icons. The Grenadier, designed for tough terrains, aligns well with Milltek’s high‑performance ethos.
Goodwood provides the perfect stage for Milltek to engage directly with car enthusiasts and media. The hands‑on experience lets customers hear and feel the difference, fostering a connection with the brand.
By providing detailed upgrades—ranging from sound tuning tips to visual finishes—Milltek addresses the growing demand for performance enhancements that don’t require sacrificing legal compliance or practicality. The Defender OCTA exhaust system exemplifies this balance.
In summary, Milltek’s new exhaust system for the Defender OCTA V8, unveiled at Goodwood, represents a synergy between performance engineering, sound design, and street-legal functionality. It stands as a strong example of how aftermarket brands can enhance high-end vehicles while respecting compliance standards.
