Exhaust Mercedes V-Class W447 (2014-Today)

The Mercedes V-Class W447, produced since 2014 with restylings in 2019 and 2023, uses a variety of engine types including 4-cylinder diesel (OM 6xx series), petrol, and electric variants (EQV/eVito). Compatible exhaust systems include original and aftermarket silencers, mufflers, flexible pipes, and tailpipes designed specifically for these engines while meeting Euro 6 emissions standards.

The vehicle’s dimensions and chassis design impact exhaust system profiles and components. Wheelbases vary between 3200 mm and 3430 mm, affecting overall exhaust length and routing. The diesel engines normally feature turbochargers and intercoolers, paired with DPFs to ensure compliance with Euro 6 emission standards. Aerodynamics (with a frontal surface of 3.24 m² and drag coefficient of 0.32) also influence exhaust outlet design.

Original exhaust components for the Mercedes V-Class W447 include:

• Silencers/mufflers (e.g., references A4474900201 and A4474902081 for 2.0L diesel 2019 models)
• Flexible pipes with 55 mm inner diameter and 200 mm length for 2014-2020 models
• High-quality OE equivalent rear silencers such as MTS 01.96670

These parts ensure proper system function and emission control compliance.

Yes, there are stainless steel sport exhaust options designed for improved sound, weight reduction, and airflow, including:

• PIECHA stainless steel silencers with 4 oval outlets for diesel W447 (3200 mm wheelbase)
• Fox Exhaust duplex silencer, stainless steel, with twin 80 mm outlets (reference MB082006-070-1)
• Other sport silencers emphasizing OE-like quality and fitment

These are designed specifically for the vehicle's diesel variants, providing a sportier sound profile while maintaining durability and emission conformity.

Exhaust systems for diesel engines in the W447 feature Diesel Particulate Filters (DPF) and catalytic converters engineered to meet Euro 6 emissions standards. These are integrated with turbocharging and intercooling technology to ensure efficient exhaust gas treatment.

• DPFs capture particulate matter to reduce pollution
• Catalytic converters process harmful gases like NOx and CO
• Systems are designed for optimal backpressure and airflow to maintain engine efficiency and reduce emissions

It is essential to use compatible and certified exhaust parts to ensure legal compliance and vehicle performance.

One notable issue was linked to a diesel emissions scandal in 2018 involving the 1.6L OM622 diesel engine variant. A device that illegally altered exhaust gas processing was detected, leading to recalls impacting 6300 vehicles. This highlights the importance of genuine, compliant exhaust components for proper emissions control.

Regular checks and maintenance of the catalytic converter and DPF are recommended to ensure continued compliance and performance.
