The CAPRISTO system includes the muffler and the back pressure control unit, and is only designed to suit the Porsche 987 Boxster - First Generation.

This system can be fitted to the OEM headers, it is a simple "bolt-on" installation..

It features a programmable control unit also referred to as CAPRISTO Exhaust Control Box. The box is programmable via a remote control to fit the vehicle's or the customer's needs. It monitors the back pressure of the exhaust gases and makes sure the best possible performance is delivered.

This system is sold with the CAPRISTO Programmable Remote Control System.

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.

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 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.

Made of high-grade T309 (1.4828) stainless steel (close to Inconel properties) throughout the entire system and the entire system is then hand polished to a mirror finish.
