Valved Cat Back Exhaust - Mercedes G Wagon G63 2019-2024 (W463A)

The Milltek Sport Cat-Back Exhaust System is a premium sound and performance upgrade for the Mercedes-AMG G63 W463 (2019-2024).

Designed to bring out the deep V8 character of the G63, this system delivers a stronger, more aggressive exhaust note while improving flow over the factory setup. Built from high-quality T304 stainless steel, the Milltek exhaust is made for long-term durability, clean fitment, and a refined performance sound.

The system uses 76 mm mandrel-bent tubing to help reduce back-pressure and improve exhaust flow. This supports better turbo response, sharper throttle feel, and a more engaging driving experience without compromising daily usability.

One of the key benefits of this exhaust is its compatibility with the factory electronic valve system. It works with the original valve actuators, allowing the driver to switch between a more controlled street tone and a louder performance sound using the factory cabin controls.

The side-exit design keeps the signature G63 look while adding a more purposeful presence. Multiple tip finish options are available, allowing the system to match the style of the build, from clean OEM+ to more aggressive blackout or performance-focused setups.
