The Fabspeed Motorsport Forza Electronic Exhaust Valve Controller Kit for Ferrari 488, California T, and GTC4Lusso T models is a complete plug-and-play solution that gives drivers full manual control over their factory vacuum-actuated exhaust bypass valves. Designed to override factory ECU-controlled valve operation, this advanced controller allows you to customize your Ferrari’s exhaust sound at any time while maintaining the ability to instantly return to factory functionality.

At the heart of the system is a high-reliability electronic control module that manages the negative side of the factory exhaust valve vacuum solenoids. This enables precise control of valve position, allowing drivers to open the exhaust valves for maximum exhaust sound and performance character or close them for a quieter driving experience.

Whether you're looking to enjoy the unmistakable Ferrari exhaust note at all engine speeds or reduce sound levels for specific driving environments, the Forza Controller provides complete flexibility through multiple operating modes.

Built specifically for the demanding conditions found in high-performance engine bays, the controller features a rugged extruded aluminum enclosure and a high-temperature-resistant internal circuit board. Premium TPE-insulated wiring and weatherproof automotive connectors ensure reliable operation in harsh environments exposed to heat, moisture, oil, and vibration.

Installation is completely plug-and-play and requires no cutting, splicing, ECU programming, or permanent vehicle modifications. The included harnesses connect directly to the factory exhaust valve vacuum solenoids, making installation straightforward and fully reversible.

The included remote transmitter allows instant control of exhaust valve operation, while users also have the option of configuring a manual on/off switch inside the vehicle if desired.

Operating Modes

• Normal Mode: Exhaust valves operate exactly as intended by the factory ECU
• Always Open Mode: Forces the exhaust bypass valves to remain fully open at all times for maximum exhaust sound
• Always Closed Mode: Forces the exhaust bypass valves to remain fully closed for quieter operation

The Always Closed mode is particularly useful for track events and driving environments with strict sound restrictions where reduced exhaust noise is required.
