Rear silencer Capristo Audi S4 / S5 F5

02AU03103011, 02AU03103016

Valved rear silencer for the Audi S4 and S5 of the F5 and B9 series with the 3.0 TFSI EA839 turbocharged V6. The turbocharger absorbs much of the sound before the exhaust begins, so the rear section decides how much of the engine reaches the driver.

Two versions

• With carbon tailpipes and CES-3 controller (02AU03103011);
• With CES-3 controller and ECE approval (02AU03103016).

The CES-3 switches the valves from the key fob and from a handset in the cabin, independent of the driving mode.

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.

Material and build

T309 (1.4828) stainless steel, rated above 600 C, hand TIG welded and polished to a mirror finish in Sundern, Germany.

Before you order

• The ECE approved version keeps the car street legal in Europe;
• The silencer works with the standard mid-section or with Capristo pipes;
• Installation uses the original hangers and is reversible.

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