For vehicles with two vacuum control valves.
Three-way exhaust controller suitable for installation in harsh environments such as the engine bay of a high-performance sports car.
Depending on application, the controller offers up to three modes of operation:
Plug-and-Play ... 100% Reversible
The kit is completely plug-and-play. Power for the controller comes from the existing connector to the car's exhaust bypass vacuum solenoids, and no wiring modification are required because the kit includes connector cables for the vacuum solenoids. Since no modification 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 is straight forward. The small size makes it easy to find a suitable location to install the controller. Unplug the existing connectors to the vacuum solenoid valves, connect the included Y-cables and route the cables to the controller. 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.
The Model B4 Controller has two connectors and is designed for cars with two vacuum control valves. The Model B4 can be used in place of the Model B4A. But one of the connectors will remain unused. Contact us for compatibility with other vehicles not listed above.
