Milltek Valved & Non-Resonated Catback Exhaust System for L663 Land Rover Defender V8 90
Milltek’s Valved Non-Resonated Catback Exhaust System for the L663 Land Rover Defender V8 90 unleashes the full sound potential of the 5.0L supercharged engine with a louder, more aggressive exhaust note under throttle. By removing the resonators, this system delivers a raw, high-impact tone while retaining valve-controlled refinement for quieter cruising when needed. Built from 2.76-inch mandrel-bent pipework to maximize flow and minimize backpressure, it’s fully compatible with both OPF / GPF and non-OPF / non-GPF setups. Quad 90mm tailpipes are available in a range of premium finishes — Polished, Cerakote Black, Carbon Fiber, Brushed Titanium, and Burnt Titanium — allowing for a personalized, motorsport-inspired look. Designed for enthusiasts seeking bold acoustics and performance without compromise, this system transforms the Defender V8 90 into a more visceral and engaging drive.
