Rear silencer with middle silencer delete pipes Capristo Audi S8 D4

02AU09403001

Rear silencer with middle silencer delete pipes for the Audi S8 D4 with the 4.0 TFSI EA824 biturbo V8. The kit replaces both the rear silencer and the middle section, so the whole back half of the exhaust is changed at once.

What is in the kit

• Valved rear silencer;
• Replacement pipes for the standard middle silencer;
• EVCU-1 control unit for the valves.

The EVCU-1 drives the valves independently of the car's own control, so the mode is chosen on demand rather than tied to the driving programme.

How it works

The valves stay closed at light load, so cruising noise stays close to the quiet an S8 is built for. 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.
