Pre-silencer delete pipes Capristo Audi S4 / S5 B8 V6

02AU03103009

Pre-silencer delete pipes for the Audi S4 and S5 of the B8 series with the 3.0 TFSI EA837 supercharged V6. These lightweight pipes fit in place of the heavy original pre-silencer, the damping chamber that sits ahead of the rear section.

What changes

Removing the pre-silencer takes a flow restriction out of the middle of the system and drops weight with it. The damping effect of that chamber disappears, so what the rear silencer lets through is no longer pre-softened and the engine is heard more directly.

Material and build

T309 (1.4828) stainless steel, rated for continuous temperatures above 600 C, hand TIG welded and polished in Sundern, Germany. The pipes are developed on 3D laser scans of the original part and go into the existing mounting points.

Before you order

• The pipes only work together with the Capristo exhaust system, not with the standard rear section;
• They fit the V6 cars only, the V8 B8 has a different layout;
• Capristo supplies them for off-road and track use;
• Installation is reversible, the standard pre-silencer can be refitted.

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