Exhaust Valve Control Kit

The Capristo Exhaust Valve Remote Control Kit is an essential electronic upgrade for the Ferrari California T. Designed to bypass the conservative factory ECU constraints, this plug-and-play module hands total acoustic control over the 3.9L twin-turbo V8 back to the driver. It requires no ECU reprogramming and is fully reversible, allowing you to unlock or mute your exhaust at the press of a button.

The Acoustic Challenge & Remote Control Logic

From the factory, the California T's exhaust valves operate under strict parameters managed by the onboard ECU, which typically mutes the twin-turbo V8's voice during city driving.

The Capristo Remote Kit overrides this digital logic using a specialized remote key fob with the following functional layout:

• Button 1 (OEM Valve Control): * Valves Closed Mode: Switches back to the factory-managed settings, keeping the exhaust valves shut even under load until they naturally need to open depending on your selected driving mode (e.g., in Race mode they will open significantly earlier than in Comfort). This profile is ideal for quiet startups, navigating residential areas, or long-distance motorway cruising.
• Button 2 (Permanently Open Mode): * Valves Open Mode: Forces the valves open regardless of your current RPM, speed, or factory drive mode. This provides full, unrestricted exhaust sound at all times—even at a complete standstill/idle.
• Buttons 2 & 3 Together (Memory Save): * Pressing these buttons simultaneously saves the current valve position as the default standard configuration. For example, you can program the system to automatically start the vehicle with the valves fully opened every time you turn the key.

Technical Engineering & Safety Features

• True Plug-and-Play Integration: Supplied with vehicle-specific wiring harnesses featuring genuine Ferrari OEM-style plugs. It draws power directly from the original harness, requiring zero wire cutting or splicing.
• Non-Invasive Architecture: Because the module operates independently of the car's engine management computers, it requires no software flash or re-tune and can be removed at any time without leaving a digital trace.
• Integrated Fail-Safe System: Safety is paramount in high-performance turbocharged applications. The Capristo control unit features an automated fail-safe layout. In the rare event of a vacuum loss or an electrical interruption, the system defaults to the fully open position to prevent excessive heat buildup, safeguarding the turbochargers and engine headers.
