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 engine ECU, therefore working in the same way that the original exhaust was designed to function. On the Portofino the OEM Valves are controlled electronically.? The CAPRISTO E2P Remote (Electronic to Pneumatic) connects to the OEM plugs and uses solenoids to open the patented CAPRISTO Valves on the new exhaust system.
The Capristo E2P Remote Kit for the Portofino’s Electronic exhaust valves, provides the ability to open and close the valves at a touch of a button. In the “closed position” control is returned to the engine ECU.
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).
