The 3-Way Controller Gives You Complete Control of the Dual Mode Exhaust on your Camaro or Corvette

$164.50 USD


Three Operational Modes

The 3-Way Controller is a new development which will give you three different operational modes:

  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. 

As with our other exhaust controllers, you can use the included wireless remote transmitter ... OR ... you can choose to use a manual switch.  The Forza controller allows you to use either one.

Plug-and-Play  ... 100% Reversible

Completely plug-and-play.  No wiring modification is required.  All necessary wiring and mounting accessories are included.  There is no electrical modifications required to your vehicles.  No wire cutting or splicing.  The electrical system on your vehicles will not be compromised.  All your existing devices and connections will have no changes.  Once installation is complete, you use the buttons on your remote transmitter to select the operational modes   ...  and, you also have the ability to configure a manual switch that you can mount inside your vehicle. 

Since no modification to the vehicle or vehicle's electrical system is required to install, if you ever want to remove the controller the installation is 100% reversible.

Simplified Installation

Installation is quick and simple.   You only need to select a location to install the controller and connect the power cable.  On the Camaro, power is obtained from the fuse block is in the rear of the car.  On the Corvette, power is from the fuse block located under the instrument panel.  Simply unplug the vacuum solenoid,  connect the included cable and route the cable to the controller.  Once installation is complete, you use the buttons on your remote transmitter to control the exhaust bypass valves  ...  and, you also have the ability to configure a manual on/off switch that you can mount inside your vehicle.
