Exhaust Valve Controller

The Forza Exhaust Bypass Valve Controller Kit, designed for the Lamborghini Gallardo (B3A and B4A models), allows you to take full control of your exhaust note. This system provides three distinct operational modes selectable via an included remote transmitter or an optional manual switch. In Normal Mode, the vehicle's ECU dictates when the exhaust bypass valves open or close, maintaining stock operation. Selecting Always Open mode forces the valves to remain in the open position, delivering the full, unrestricted sound of your engine at all times. For situations requiring maximum quietness, such as noise-restricted track days or specific driving conditions, the Always Closed mode forces the exhaust bypass valves to stay shut, overriding the factory ECU settings. The TPE-insulated cabling is rated to 105°C, and all electrical connectors are weatherproof to resist moisture. The kit is completely plug-and-play, drawing power from the existing exhaust bypass vacuum solenoids and including necessary connector cables, ensuring no permanent wiring modifications are needed. This makes the installation entirely reversible if desired. Installation involves locating a suitable spot for the compact controller, unplugging the factory vacuum solenoids, connecting the provided cables, and routing them to the controller. The included remote has dedicated buttons to open or close the valves, returning control to the car's ECU when closed.
