Exhaust system Capristo Audi RS4 B8

02AU05203001, 02AU05203011, 02AU05203002

Exhaust system for the Audi RS4 B8 Avant with the 4.2 FSI V8. The last naturally aspirated RS4 keeps a heavy standard silencer, and this is the part of the car where the engine loses most of its voice.

Three versions

• Standard system (02AU05203001);
• System with ECE approval (02AU05203011);
• Rear silencer only, with ECE approval (02AU05203002).

The silencer-only option is for owners who want to keep the standard mid-section and still get valve control at the back.

How it works

The valves stay closed at light load, so cruising noise is close to standard. Opened, the gas path shortens and bypasses the damping chambers, which is where the volume and the sharper response come from.

Material and build

T309 (1.4828) stainless steel, hand TIG welded and polished to a mirror finish in Sundern, Germany, developed on 3D laser scans of the original pipework.

Before you order

• The ECE approved versions keep the car street legal in Europe;
• Tailpipes are chosen separately;
• The system is lighter than the stock parts it replaces;
• Installation is reversible.

Capristo Automotive GmbH has built valved exhaust systems since 1990 and holds several patents on its valve technology.
