The Capristo Valved Dual Mufflers for the W463 Mercedes-AMG G63 give the G-Class a more expressive voice shaped around control, clarity, and responsiveness. The 5.5-liter twin-turbo V8 already delivers a commanding presence, and Capristo builds on that foundation with a system tuned to keep the note deep during relaxed driving while opening into a richer sound as the throttle rises.

At lower speeds, the tone settles into a smooth and composed resonance that fits the luxury side of the Mercedes-AMG G63. As the RPM climbs, the sound gains intensity in a clean and deliberate way, avoiding the harsh tone changes common in lesser systems. Capristo focuses on natural transitions, creating a sound that feels connected to the engine rather than forced by the hardware.
Every component is designed with accuracy, and the G-Class benefits from this refined approach. The system flows more efficiently, reacts faster to valve changes, and maintains long-term durability under the heat of turbocharged operation.
Capristo’s vacuum-actuated valves are responsible for most of the system’s character. These valves respond to throttle position and engine load, switching between closed and open states depending on how the Mercedes-AMG G63 is being driven. In everyday traffic, the valves stay closed to maintain a deep, controlled tone. Under heavy throttle, they open and let the full sound of the twin turbo V8 come through.
The CES-3 control module adds another layer of customization. Through a remote key fob, the driver can choose between Cruise, Sport, and Open modes. Cruise delays valve opening until higher RPM. Sport opens the valves earlier under load. Open keeps them fully open. The module allows both Cruise and Sport to be programmed by adjusting backpressure thresholds, giving owners the ability to tailor how the G63 responds in real conditions.
This adjustability makes the system feel like a custom sound setup built specifically for the driver.
Capristo uses 3D laser scanning, CAD modeling, digital design, and CNC machining to shape each part specifically for the W463 chassis. The system is built from T309 stainless steel, chosen for its heat stability, acoustic quality, and fatigue resistance. This material mirrors traits found in high-performance motorsport components, giving the Mercedes-AMG G63 a durable and acoustically transparent exhaust.
The finish is hand-polished, and installation uses factory mounting points for a clean, secure fit. The system is engineered for 2012 to 2018 Mercedes-AMG G63, G500, and G550 models, providing exact alignment with OEM geometry.
The improvement in tone, responsiveness, and quality is immediately noticeable once installed.
The Capristo Valved Dual Mufflers for the Mercedes-AMG G63 are available through Bulletproof Automotive. This upgrade brings sharper tone, adjustable valve control, and long-lasting craftsmanship to the W463 G-Class, refining the sound and giving the SUV a more engaging personality on every drive.
