Forza Model E3 Exhaust Controller

Model E3 Controller

Forza model e3 exhaust controller


The Model E3 has the same functionality as the Model B3A.  The E3 Controller is a 3-way exhaust controller that is designed for installation in moderate environments such as the interior of the car or an exterior location not directly exposed to high heat.

The Model E3 Valve Controller provides three different operational modes — each mode  can be selected using the included remote transmitter or a manual On/Off switch.

  1. Normal Mode:  In this mode, the vehicle controls the operation of the exhaust bypass valves.  This is the stock operation. 
  2. Always Open:  Selecting this mode will force the exhaust bypass valves to the open position — and remain open.  When the valves are Always Open, you have the full experience of hearing your engine exhaust at any time.  
  3. Always Closed:  Selecting the Always Closed mode will force the exhaust bypass valves to remain closed at all times.  This overrides the ECU control which opens the valves at predetermined engine and vehicle speeds.  This mode is especially useful to ensure that your vehicle is as quiet as possible.  Note: With this option, you can force the valves to stay in the closed position at all times.  This feature was added at the request of people who track their cars at locations with strict noise standards and did not want the vehicle ECU to open the valves at high engine RPM. Note:  When used on Alfa Romeo Giulia QV or Stelvio QV, the always closed mode is disabled
