Description

Part #: MER.GWAG.W463A.VSES.AG

The modern G-Wagon is a symbol of power, presence, and luxury but its factory exhaust leaves much of the AMG character muted. The Valvetronic Designs Valved Exhaust System transforms the G63 into a snarling beast while retaining the refined manners you need for long drives. Inspired by the AMG GT-R's visceral tone, this system was developed from the ground up to deliver an uncompromising blend of aggression, refinement, and daily usability.

Features:

  • Constructed from T304 stainless steel with anodized gold finish
  • Fully mandrel-bent piping for optimal flow
  • Electronic exhaust valves with OEM integration
  • Acoustic Design:Tuned for a naturally aspirated-style character while maintaining the muscular presence of the 4.0L bi-turbo V8.
