T304 Stainless Steel • Valvetronic Control • AMG V8 Sound Redefined
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.
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.
Enhanced Flow Dynamics: Optimized design reduces backpressure for faster turbo spool, improved horsepower, and torque gains across the rev range.
T304 Stainless Steel: Premium-grade construction for strength, durability, and corrosion resistance in all driving conditions.
Precision TIG Welding & Mandrel Bends: Maximum flow efficiency and flawless craftsmanship.
OEM or Independent Valve Control: Integrated with factory electronics for seamless operation via drive modes, or use our valve control unit for full control at the press of a button
100% Reversible: Bolt-on installation allows a return to stock configuration at any time.
Performance Unleashed: Unlock the full potential of the 5.5L AMG Bi-Turbo V8.
Sonic Perfection: Aggressive yet refined tone that defines AMG’s character.
Luxury Meets Control: Valvetronic technology gives you sound on your terms.
