Mercedes W463 G63 AMG – Valved Exhaust System
T304 Stainless Steel • 2.75" Free-Flow
Overview
The W463 G63 AMG, with its 5.5L twin-turbocharged V8, is already an icon. But the stock exhaust doesn’t capture the raw aggression that an AMG should deliver. Enter the Valvetronic Designs Valved Exhaust System—engineered from anodized gold T304 stainless steel and designed to transform your G-Wagon into an auditory masterpiece. With a 2.75" free-flow design and stunning carbon fiber tips, this system delivers the brutal soundtrack and presence the G63 deserves.
Sound & Control
-
Valves Open: Aggressive, naturally aspirated-inspired tone reminiscent of the legendary M156 6.2L V8. Raw, powerful, and commanding.
-
Valves Closed: Quiet, docile, and refined—so subdued you’d mistake it for a G320 CDI. No drone, no compromise.
-
With Free-Flow Front Pipes (optional): Maximum aggression, turbo spool symphony, and a cabin filled with thrilling tone throughout the rev range.
Performance Engineering
-
Optimized Flow: 2.75" mandrel-bent tubing reduces backpressure and sharpens throttle response.

-
Precision Craftsmanship: TIG-welded throughout for durability and longevity.
