Milltek Valved & Resonated Catback Exhaust System for L663 Land Rover Defender V8 90
Milltek’s Valved & Resonated Catback Exhaust System for the L663 Land Rover Defender V8 90 transforms the tone and character of the 5.0L supercharged engine with a deeper, more assertive sound under acceleration, while maintaining refined acoustics during cruising thanks to its active valve control. Crafted from 2.76-inch mandrel-bent pipework for improved flow and reduced backpressure, the system is fully compatible with both OPF/GPF and non-OPF/GPF configurations. Quad 90mm tailpipes are offered in a variety of premium finishes — Polished, Cerakote Black, Carbon Fiber, Brushed Titanium, and Burnt Titanium — providing a tailored aesthetic to match the Defender’s bold design. Balancing aggressive tone with everyday usability, this system elevates both the auditory and dynamic experience of the Defender V8 90.
