Mercedes CLS 63 AMG – Valved Sport Exhaust System
T304 Stainless Steel • Valvetronic Control • AMG V8 Sound Redefined
Overview
The Mercedes-Benz CLS 63 AMG is already a masterpiece of performance and design, powered by the legendary 5.5L Bi-Turbo V8. At Valvetronic Designs, we’ve engineered a valved stainless steel exhaust system that elevates this powerhouse to an entirely new level—delivering more performance, more engagement, and complete control over your sound experience.
This system is designed for those who want the best of both worlds: spine-tingling aggression when the valves are open and refined luxury when it’s time to fly under the radar.
Sound Dynamics
-
Valves Open: Unleash a raw, motorsport-inspired tone with thunderous growls, sharp crackles, and an exhaust note that reflects AMG’s racing DNA.
-
Valves Closed: A quieter, more subdued tone perfect for city driving, long-distance comfort, or when you want to preserve the CLS 63’s luxurious nature.
-
Drone-Free Experience: Meticulous acoustic tuning ensures a cabin free of unwanted drone, keeping every drive comfortable.
Performance & Construction
