Porsche987 Boxster (before 2009) Valved Exhaust System Cat Back (Incl. Remote)
The CAPRISTO system includes the muffler and the back pressure control unit, and is only designed to suit the Porsche987 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.
This Package Includes:
– Porsche 991.2 GT3RS Valved Middle Silencer Spare Pipe
This modular CAPRISTO performance system is intended to increase between power, drive ability and sound quality, without forgetting of course a substantial loss of weight. All of this is delivered while maintaining the CAPRISTO best of both worlds philosophy which provides the capability to produce an aggressive exhaust note under acceleration and a more subdued sound for city driving.
- Porsche Cayman 987 MK1 High Flow Headers
- Porsche Cayman 987 Mk1 High Flow Cats
- Porsche Cayman 987 Mk1 Valved Exhaust System
The iconic CAPRISTO Valved Exhaust System offers the best of both worlds through its capability to produce an aggressive exhaust note under acceleration, and a more subdued sound for city driving. At lower engine speeds and during cruise operation the valves are closed and produce a deeper exhaust note. At wide-open throttle the valves open, releasing the full symphony of the engine.
The opening or closing of the CAPRISTO valves are controlled by the CES-3 Programmable Control Module, which provides the ability to open and close the valves at a touch of a button.
The programmable control unit provides 3 modes operated via a remote key fob:
Cruise Exhaust valves open at higher RPMs
Sport Exhaust valves open at lower RPMs and hard acceleration
Open Exhaust Valves Remain Open
Both the Cruise and Sport mode can be individually programmed for specific backpressure allowances to determine when the exhaust valves open. This allows precise control of the exhaust based on the drivers personal tastes and tolerance.
CAPRISTO Exhaust systems are engineered and manufactured utilizing advanced 3D Laser-Scanning, CAD Design, Digital prototyping, and CNC-bending/milling at our factory in Germany. Each system is made of high-grade T309 (1.4828) Stainless Steel and hand polished to a mirror finish. After extensive research, this specific alloy was chosen for its sonic resonance properties, low weight, and durability which are close to the properties of Inconel (used in F1).
