MERCEDES-BENZ E400 AMG SPORT PLUS AUTO
Refined Performance of the Mercedes-Benz E400 AMG Sport Plus Auto
The 2014 Mercedes-Benz E400 AMG Sport Plus Auto combines executive comfort with strong twin turbo V6 performance. To further enhance its character, a full Mercedes Benz Exhaust upgrade was carried out, including a complete decat conversion and a custom straight through pipe system with an integrated valve. Removing the catalytic converters and restrictive sections allows the 3.0 litre twin turbo engine to breathe more freely, improving exhaust flow and sharpening overall engine response. The addition of a valved setup gives the driver full control over the sound level, refined when cruising and aggressive when opened up.
Advanced Features and Dimensions
With adaptive suspension and multiple driving modes, the E400 already delivers a balanced and composed drive. The upgraded Mercedes Benz Performance Exhaust complements these features by reducing back pressure and enhancing turbo efficiency, helping the engine feel more responsive throughout the rev range. The valved system maintains everyday usability while delivering a deeper and more pronounced exhaust tone under acceleration.
Competitive Luxury Segment Performance
Competing with models such as the BMW 5 Series and Audi A6, the E400 AMG Sport Plus stands out for its smooth power delivery and strong mid range torque. The decat and straight pipe conversion transforms the vehicle’s performance character, producing sharper throttle response and a far more engaging driving experience, while still retaining the refined comfort expected from a luxury saloon.
Enhance Driving with DKU Performance Exhaust Systems
This custom Mercedes Benz Exhaust System upgrade delivers improved airflow, reduced restriction, and a commanding exhaust note. The result is a more responsive, free revving engine paired with a dynamic sound profile that can be adjusted instantly via the valve system, perfectly balancing performance with everyday practicality.
