Mercedes-Benz AMG GT63 Stainless Valved Cat-Back Exhaust System

Elevate your AMG GT63 with a cat-back exhaust that delivers power, control, and presence.

Our stainless steel valved cat-back exhaust system is engineered to complement the twin-turbo V8 performance of the Mercedes-AMG GT63. Featuring electronic valve control, this system gives you complete command over your exhaust note—from refined luxury cruising to full-throttle aggression—while optimizing flow for measurable performance gains.

Key Features:

• Premium T304 stainless steel construction for superior corrosion resistance and longevity
• Electronic valve control for switchable sound profiles
• Cat-back design replaces restrictive factory components from catalytic converters to tips
• Optimized piping diameter and routing for improved exhaust flow and turbo efficiency
• Precision-mandrel bent tubing maintains consistent velocity and minimizes turbulence
• Direct bolt-on fitment with all mounting hardware and gaskets included
• Hand-welded and TIG-finished for exceptional build quality
• Reduced weight compared to factory exhaust system

Performance Benefits:

Enhanced exhaust flow reduces backpressure, allowing the twin-turbo V8 to breathe more efficiently. Expect improved throttle response, power delivery across the rev range, and a more engaging driving experience.

Sound Character:

Deep, refined tone with valves closed for daily driving. Open the valves to unleash an aggressive, race-inspired exhaust note with pronounced turbo spool and crackles on overrun.

Fitment: Mercedes-AMG GT63 / GT63 S (X290)
