Exhaust Capristo Porsche GT2

Capristo Porsche GT2
Exhaust system for the Porsche 997 GT2 and the 997 Turbo. The system, made from T309 (1.4828) stainless-steel, has a valve-controlled unit and is back pressure optimized. Next to it is streamline optimized and comes with two 200 cell metal sport catalysts (OBD suitable). The two ceramic-coated end pipes finish up the look of the system.


The system has a programmable control unit also referred to as Capristo Exhaust Control Box available. 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.

An additional 60Nm – 90Nm and approximately 20hp increase was measured in the lower range of rpm. In the upper range of rpm’s it was an increase of approximately 15hp.

The muffler is back pressure-controlled and freely programmable. This means that there is a control unit for monitoring the back pressure. This control unit provides the possibility to individually program the pack pressure one would like to drive in. This way, one can reach the maximum performance. The portion of back pressure resulting in a loss in performance is filtered out.
Therefore, this sports exhaust combines all advantages in both the lower and higher range of revolutions (rpm), since the back pressure can be exactly dosed 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 ,Italian) and provides 3 basic modes to be operated via a remote control, namely

a) Cruise mode - the exhaust gas valves open later
b) Sports mode - the exhaust gas valves open earlier
c) 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.
