Exhaust Mercedes Viano W639 (2003-2014)

The Mercedes Viano W639, produced between 2003 and 2014, supports various exhaust components including standard silencers, sport silencers with stainless steel options, flexible pipes, and replacement parts tailored for diesel engines like 2.2 CDI, 3.0 CDI, and 3.2 CDI (OM642.990) with power ranging from 204 to 224 hp.

Sport exhaust silencers, such as the PIECHA 4-outlet oval design in stainless steel, are designed especially for long wheelbase Viano/Vito W639 models. These improve sound quality and vehicle aesthetics, fitting engines including 2.2 CDI, 3.0 CDI, and 3.2 CDI variants.

Standard exhaust parts cover various stainless steel silencers and pipes, including:

• Specific silencers for CDI 3.0 engines with lengths around 1080 mm and compatibility with SWB/LWB versions
• Generic silencers suitable for Vito/Viano W639 models
• Replacement exhaust pipes matching OEM standards

These parts satisfy strict European emission norms and fit within regulated manufacturing quality for diesel vehicles.

Flexible pipes absorb engine vibrations, noise, and thermal expansions between key exhaust system components like the engine, silencers, and catalytic converters. These pipes come in various interior diameters (35mm, 45mm, 55mm, 60mm) and lengths (100mm to 300mm), ensuring compatibility with Viano W639 models from 2003 to 2014.

Fitment depends on your engine type, production year, and vehicle length (SWB or LWB). Always check your vehicle's VIN and engine details against part specifications. Exhaust parts comply with Euro emission standards with components like the catalytic converter and DPF designed for exact power outputs.

• Consult manufacturer or trusted shop product data sheets
• Verify part numbers and compatibility by engine code (e.g., OM642.990)
• Use professional technical support if needed

This process ensures the exhaust system maintains proper function, sound, and emissions control.

High-quality exhaust products are typically made from stainless steel (INOX 409 grade) to resist corrosion and ensure durability. Catalytic converters and DPFs incorporate advanced ceramic monoliths treated with rare metal coatings to provide superior emissions filtering performance.

These materials contribute to long-lasting, efficient exhaust systems with stable engine power output and reliable pollution control.

• Stainless steel pipes and silencers for corrosion resistance
• High-grade ceramics with unique thin-layer coating technology for catalytic converters and DPFs
• Flexible pipes designed to withstand vibrations and thermal expansion

Such quality controls align with European regulations and automotive certification standards.
