Model B5 Controller


Two-way exhaust controller suitable for installation in harsh environments such as the engine bay of a high-performance sports car.

The controller provides two modes of operation:

  1. Normal Mode:  The vehicle controls operation of the exhaust bypass valves.  This is the stock mode.
  2. Always Open Mode:  Forces the valves to remain open at all times, overriding the vehicle's ECU.



Plug-and-Play  ... 100% Reversible

The kit is completely plug-and-play.  Power for the controller is provided by a separate power connection from the vehicle's fuse box. The kit includes a fuse tap and instructions for connecting to the fuse box. No wiring modifications are required.  Since no modifications are required to install, if you ever want to remove the controller the installation is 100% reversible.

Start-up option user configurable for Always Open or Normal Mode (ECU Control).

Simplified installation

Installation is straight forward.  The small size makes it easy to find a suitable location to install the controller.  Using the provided accessories, establish electrical connection and route wires.  Once installation is complete, you use one button on your remote transmitter to open the exhaust bypass valves and the other button to close the valves and return control to the car  ...  and, you also have the ability to configure a manual on/off switch that you can mount inside your vehicle.
