Mercedes AMG GT 43 – Valved Stainless Steel Exhaust System

T304 Stainless Steel • Valved Control • Inline-6 Sound Transformation

Overview
The AMG GT 43 is a showcase of engineering brilliance, blending AMG performance with luxury and refinement. But while the single-turbo inline-6 engine delivers efficiency and smoothness, its factory exhaust doesn’t live up to AMG’s heritage of sound. The Valvetronic Designs Valved Stainless Steel Exhaust System changes that—unlocking a sharper response, improved flow, and a sound signature that finally matches the AMG GT 43’s character.

  • Valves Closed: Quiet, refined, and luxurious—ideal for city cruising or long-distance comfort.

  • Drone-Free Tuning: Meticulously engineered to eliminate cabin drone for everyday usability.

Performance Engineering

  • Enhanced Flow Dynamics: Free-flowing 3.0" design reduces backpressure for quicker throttle response.

  • Optimized Turbo Integration: Works in harmony with the inline-6’s turbocharger, improving efficiency and torque across the rev range.

  • Precision TIG Welding: Ensures strength, durability, and a flawless finish.

Construction & Craftsmanship

  • Material: T304 stainless steel for long-term durability and corrosion resistance.

  • Design: Polished finish with exacting fitment from factory connections to the outlet.

ECU tuning works by modifying the software that controls engine parameters like fuel mixture, ignition timing, and boost pressure to optimize performance.

The process of installing a tune depends on the vehicle’s make and model. Some tunes are installed by connecting a tuning device to your car’s OBD-II port and uploading the tuned software, others may require ECU unlock.

Stage 1 is for vehicles with no modifications, stage 2 is for vehicles with bolt-on upgrades or downpipes installed.

We offer post-installation support, troubleshooting, and guidance on using your tuning software and hardware.

Choose tuning software that is compatible with your vehicle, has good reviews, and suits your performance goals (e.g., reliability vs. max power).
