There’s something thrilling about hearing a V8 growl to life, and the Defender OCTA V8 exhaust from Milltek finally gives this twin-turbo beast the voice it deserves. After showcasing a prototype at the 2025 Goodwood Festival of Speed, Milltek has confirmed its sports exhaust system for production, and it’s set to elevate the OCTA experience to a whole new level.
The Sound Every Defender OCTA V8 Should Have
Let’s be honest, stock exhaust systems on modern performance SUVs often feel a bit too polite. That’s where Milltek comes in. They wasted no time acquiring their own OCTA and immediately started engineering a new exhaust to match the character of the 635 hp twin-turbocharged V8.
Using a non-resonated, particulate filter-back design, the result is a deeper and more visceral sound. The system integrates with the OCTA’s existing valve control, offering full compatibility while delivering a much more engaging acoustic profile, one that truly brings the engine to life.
Built for Power, Precision and Presence
Milltek’s new Defender OCTA V8 exhaust is crafted from T304L grade stainless steel. This not only guarantees durability but also allows for high-performance heat and corrosion resistance. The system features twin valves that are 80mm larger than the originals and a reflective rear silencer, while eliminating the center resonator for a more aggressive note.
Yet, it doesn’t compromise on refinement. The exhaust sounds assertive under throttle but remains calm and drone-free when cruising. Whether you’re on a backroad blast or a highway drive, the tone adapts, especially in OCTA mode, where the difference is instantly noticeable.
Custom Looks to Match the Sound
Milltek lets you fine-tune the look as much as the sound. Choose from optional GT100 tips in polished black, brushed titanium, or burnt titanium for a premium, motorsport-inspired finish. Prefer a more subtle style? Stick with the OE tips while still enjoying the upgraded performance.
For those who crave both visual impact and mechanical confidence, this exhaust system checks every box.
Engineered with Enthusiasts in Mind
According to Milltek’s Kev Hall, the final product delivers exactly what their team envisioned, a strong character boost without intruding on daily usability. The blend of deeper tone, refined idle, and exciting on-throttle aggression makes this more than just an upgrade, it’s a transformation.
After the strong response at Goodwood, it’s clear this exhaust is a must-have for Defender OCTA owners who want their V8 to sound as powerful as it drives.
Summary
Milltek’s Defender OCTA V8 exhaust doesn’t just enhance sound, it amplifies the personality of an already remarkable SUV. Engineered for performance and tailored for style, it turns the OCTA into the complete package for drivers who demand more from every drive.
