Description

Milltek valved cat-back exhaust system for Mercedes-AMG G63 W463 (non-GPF models). Direct factory fitment using OEM hangers, no modifications required. T304L stainless steel construction with mandrel-bent piping and hand-finished polished tailpipe trims. Electronically controlled valve allows you to switch between refined cruising and full-throttle aggression-seamless OE valve integration.

Available in resonated and non-resonated configurations. Resonated version tunes the OE resonance point for a refined tone while eliminating drone on the motorway; non-resonated delivers maximum character for closed-course and track use. Both dyno-tested for power and torque gains across the RPM band. T304L construction ensures longevity in all weather conditions.

  • Resonated cat-back: engineered tone with OE-like refinement
  • Non-resonated cat-back: full character for track and performance driving
  • Valved operation: OEM valve compatibility, intelligent throttle response
  • Polished stainless steel trims: factory-quality finish
  • Direct OEM fitment: uses factory hangers and mounting points

Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
