**Fits the 536 Cayenne (2.9L Turbo), Cayenne S (2.9L BiTurbo), and the E-Hybrid**
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.
This feature is possible using vacuum-actuated valve flaps that open and close depending on driving conditions and input from the driver. 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 exhaust valves on the 536 Cayenne Turbo are electronically controlled. The CAPRISTO E2P (Electronic to Pneumatic) Control Module gives the user 2 driving modes operated via a remote key fob:
Sport Exhaust valves open at lower RPMs and hard acceleration (Based on OEM Settings)
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 driver?s 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).
