Model E1 Controller


Two-way exhaust controller for installation in moderate environments such as the interior of the car or other locations not exposed to high temperatures.

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.

Differences Compared to Model B5

Other than price, there are two key diffences of the Model E3 compared to the Model B5.

  1. The Model E1's enclosure is ABS plastic which is not as tolerant of high temperatures as the aluminum enclosure used with the Model B5.  The E1 should be not be used in high temperature environments such as the engine bay or near high temperature elements such as the exhaust system of the car.
  2. The Model E1 will always default to the Normal mode when you turn off the ignition.  At the the next engine start, the exhaust valves will be in the Normal position (generally closed) until you press the button on the remote.  The B5 can be configured for valves open or valves normal at engine start.



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 modification are required.  Since no modification are required to install, if you ever want to remove the controller the installation is 100% reversible.

Simplified 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 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.
