Mercedes CLA-Class Catalytic Converter C117 (2013-2019)

The catalytic converter for the Mercedes CLA-Class Coupé (C117) is an essential exhaust component designed to reduce harmful gas emissions. It complies with Euro 5 or Euro 6 emission standards and is specifically adapted for gasoline (M270) and diesel engines. This part ensures optimal flow and performance of the exhaust pipe system, helping your vehicle meet environmental regulations while maintaining main engine efficiency.

The catalytic converters are designed for specific engine models within the CLA-Class C117 lineup, produced from 2013 onwards. Key compatible variants include:

• CLA 200 (M270.910, 1.6L gasoline, Euro 6)
• CLA 250 (M270, 2.0L gasoline, Euro 6)
• CLA 250 facelift (M270.920, 2.0L gasoline, Euro 5/6)
• CLA 220 CDI (diesel, Euro 6)
• CLA 250 4MATIC facelift (M270, 2.0L gasoline, Euro 6)

Each variant requires catalytic converters with specific lengths, weights, and OBD (On-Board Diagnostic) compatibility for optimal flow and exhaust pipe connections.

Signs that your catalytic converter may be failing include:

• Warning light on the dashboard flashing or remaining lit
• Reduced engine performance or power output
• Unusual exhaust pipe noises or smells
• Damage or deterioration visible on the thermal protection plate

It is advised to check the catalytic converter and replace components such as the lambda sensor to maintain optimal gas flow and performance.

To select the correct catalytic converter, you should:

• Verify your vehicle’s engine code (e.g., M270.910), model type and year
• Check emission standard compliance (Euro 5 or Euro 6) and OBD compatibility
• Use site filters or vehicle identification number (VIN) for precise matching
• Consider pipe diameter (typically 65.5 mm) and assembly side (front or rear)
• Opt for parts certified to CE/CEE or ECE/ABE regulations

Installation kits often include necessary mounting parts to ensure an optimal fit and flow in the exhaust system.

These Mercedes CLA-Class C117 catalytic converters are typically produced by manufacturers who meet strict European quality certifications. Important quality features include:

• Manufacture using stainless steel INOX 409 for maximum durability
• High-quality monoliths with coated honeycomb structures using rare metals
• Certification by European authorities like TÜV SÜD Automotive GmbH
• Compliance with E24-103R certification ensuring technical and regulatory compatibility
• Three-year warranty covering up to 100,000 km of use

Choosing certified parts ensures main engine performance and optimal exhaust flow, while contributing to pollution reduction.

Yes, there are premium options available such as metallic catalytic converters designed for optimal exhaust pipe flow and enhanced performance. For example, the CLA 250 4MATIC facelift model (2016-2018) can be equipped with a metallic sport catalytic converter system that offers:

• Metallic substrates with higher durability
• Improved performance characteristics for better exhaust gas flow
• Compliance with Euro 6 emission norms and OBD requirements

These options are designed for drivers seeking to maintain stock exhaust appearance while enhancing main engine output.

Proper installation and maintenance are crucial to ensure the catalytic converter functions efficiently. Key points include:

• Replacement should be performed by a specialized exhaust assembly centre or garage
• All associated parts such as gaskets, sensors (like lambda sensor), and injectors must be replaced simultaneously
• Follow manufacturer assembly instructions exactly
• Use copper connections for any front connections and check tightness of the entire exhaust pipe system

Negligence or improper installation can lead to premature failure and loss of warranty coverage.

High-quality catalytic converters typically come with a 3-year warranty limited to use under 100,000 km. Support highlights include:

• Warranty covers repair of the product within the manufacturer's factory
• Technical support is provided by specialists via email or phone for installation and troubleshooting
• Free return within 30 days is available for unused and unmounted products in original condition
• Professional installation invoices are required for warranty claims

This ensures customers receive durable, certified components backed by expert support for optimal vehicle exhaust performance.
