Alfa Romeo 4C Valved Exhaust System & Carbon Diffuser (Inc. Remote)
This Conversion Kit includes a Capristo valved exhaust system, a full carbon rear diffusor, a full carbon cover frame, Three Laser-Cut and Polished Stainless Decorative Covers/Mounting Parts, and the Programmable CES-3 Control Module.
The complete CAPRISTO 4C Exhaust System & Carbon Package is intended to be a balanced increase between power, drive ability and sound quality, without forgetting of course a substantial loss of weight via the included Carbon Fiber Rear Diffuser and Full Cover Frame. 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 are backpressure-controlled and user programmable via the included CES-3 Control Module. 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).
