Capristo Valve Controlled High Performance Exhaust System Inc. Remote Audi S4 S5 08-10

Capristo Valved Controlled High Performance Exhaust System are back pressure-controlled and user programmable. With a built in limiter it prevents the system from reaching dangerous pressure levels. There is a control unit for monitoring the back pressure. This control unit provides the ability to individually program the back pressure one would like to have the valves open or close.

The portion of back pressure resulting in a loss of performance is filtered out. This way, one can reach the maximum performance. Therefore, this sports exhaust combines all advantages in both the lower and higher range of revolutions (rpm), since the back pressure can be exactly controlled to enable the engine to gain the maximum performance. The programmable control unit features an illuminated display showing all functions in plain text in 3 different languages (German, English and Italian) and provides 3 basic modes to be operated via a remote control, namely:

Cruise mode - the exhaust gas valves open later

Sports mode - the exhaust gas valves open earlier

Open mode - the exhaust gas valves remain open

In both the cruise mode and sport mode, one can individually program when the exhaust gas valves shall open. One big advantage is that the control unit recognizes the driver�s operation characteristics. If the driver accelerates aggressively, this is identified by our device by the kind of back pressure that is generated, and the exhaust gas valves open immediately. Usual acceleration results in a later opening of the exhaust gas valves.

With this valve controlled exhaust, the engine performance is increased by up to 20HP. This is achieved by installing this changed exhaust system in conjunction with the exhaust pressure regulating system. In other respects the system remains in its original series production condition to conform to TUV specifications. This exhaust has the ability to go from quiet (by closing the valves) to Sound Step 3 (which is a very loud sound for Motorsport). This is done by opening the valves with the push of a button on the wireless remote control.

Note: This system includes the programmable remote and is made of 1.4828 (T309) stainless steel. It will fit both the V8 and the V6 models.
