Complete plug & play kit for Audi 20V models

This high-quality downpipe and catalyst combination kit is perfectly matched for Audi S2, RS2, S4, S6, and 200 20V engines. It is also approved by TÜV Austria and MFK Switzerland.

Scope of delivery & documentation

The kit comes with vehicle-specific accompanying documents that enable registration with the TÜV (German Technical Inspection Authority). After ordering, you will receive the necessary documents by email. Simply send us a photo of your vehicle registration document or registration certificate.

Technical specifications & performance

The installed catalytic converter is designed for engine outputs of up to approximately 550 hp . If you require higher engine output, we would be happy to advise you on suitable alternatives. Please contact us by email.

Flexible installation & compatibility

An additional V-band clamp is included in the scope of delivery to ensure easy further processing “after the catalytic converter”.

The downpipe (version without flex pipe) was specifically developed for the original RS2 manifold and other stock manifolds—as well as our EVO manifold, which is based on the original. When using the Wagner RS2 EVO manifold, slight adjustments to the wastegate flex pipe may be necessary, as this manifold is slightly thicker.

For a more convenient connection to the manifold, please select the correct version from the dropdown menu. A small adjustment (an approximately 0.5 cm aluminum tab on the gearbox) may be necessary.

A Y-connector with approximately 1 meter of pipe is also available as an option, allowing for self-connection to any existing dual-flow exhaust system. This option can also be selected from the dropdown menu.
