Audi S5 Catalytic Converter B8/8T (2007–2012)

The Audi S5 B8/8T catalytic converter is a key exhaust component designed to reduce harmful emissions from the vehicle’s engine. It helps the car comply with Euro 5 emissions standards (mainly up to 2014-2015) and some versions are compatible with Euro 6. It converts toxic gases from the engine exhaust into less polluting gases, contributing to environmental protection and vehicle emission regulations compliance.

These catalytic converters are compatible with Audi S5 models from 2008 to 2017, particularly the 3.0 TFSI quattro engine with 333 PS (245 kW), engine codes CTDA, CGWC, CGXC, CTUB. They fit Cabriolet (8F7), Sportback (8TA), and Coupé (8T) bodies. Some versions also fit related models such as A4/S4 B8 and Q5 3.2 FSI engines (codes CALA, CALB).

The main technical aspects include:

• Engine power: 333 PS (245 kW), 3.0 TFSI quattro petrol engine.
• Emission standards: Euro 5 (up to mid-2014 or end-2015), some compatible with Euro 6.
• Dimensions: Length ranges 440 to 460 mm.
• Weight: Approximately 3.2 to 3.25 kg.
• Assembly sides: Available for right and left sides of the vehicle.
• Equipped for vehicles with OBD (On-Board Diagnostics) systems.

This ensures proper fit and function for specific Audi S5 vehicles and comparable models.

Yes, there are sport catalytic converters made from stainless steel designed to enhance flow and performance. These are typically non-homologated and feature designs like 20-cell configurations. They may come with additional components such as heat shields and can enable engine remapping for performance tuning. However, they are intended for specific applications and may not comply with all legal emissions requirements.

Prices for brand-new catalytic converters for the Audi S5 B8/8T typically range between approximately 350 to 600 € including VAT, depending on the brand, side (right or left), and specific model compatibility.
