Capristo Sports Exhaust for Audi S4 / S5 V8

The Capristo backpressure monitored sports exhaust system for the Audi S4/S5 V8 (B8 & 8F Limousine, Avant, Cabriolet and Facelift) is made of 1.4828 (T309) stainless steel, has two exhaust valves and includes a programmable controller CES-3 unit.

Most valve controlled exhaust systems on the market, open and close their valves depending on set values for RPM or speed. However, the important variable is backpressure. This system allows the exhaust valves to open at pre-set exhaust gas backpressure values which means it’s always optimised for the engine’s power.

Once fitted, this Capristo has the ability to recognise your driving style. The valves will open immediately if you push down on the pedal a bit too aggressively, recognising the build-up of pressure, but will open later under normal braking conditions.

The CES-3 valve controller has three programmable modes; ‘Cruise’, ‘Sport’ and ‘Open’ where you can determine the threshold and which can be alternated by key-fob remote controllers. You can also pre-set a ‘Favourite’ mode which determines how your car starts up. Information about pressure or mode can be displayed on the car radio via RDS and the Capristo Control Software has been developed for any advanced configuration.
