Capristo OEM Valve Controlled Exhaust No Remote Maserati Quattroporte 04-12

Capristo has designed a back pressure monitored exhaust system with two exhaust valves (programmable remote control NOT INCLUDED) was designed for the Maserati Gran Turismo (fits also to the Gran Turismo S). The Capristo exhaust is made from 1.4828 (T309) stainless steel.

This system is intended for use on vehicles that come factory equipped with a valved exhaust. It is the same exhaust system as available with the pressure monitoring system, but it ships without it, as the vehicle already has the ability to open the valves.

The exhaust valves are back pressure-controlled and user programmable. A built in limit prevents 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.
