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

• 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.
