Improved function over our original Model B1 — Now with full 3-Way function using either the included remote or a manual 3-way switch.
Kit is a complete solution that allows The Model B2 controller replaces our original Model B1. The Model B2 Exhaust Bypass Valve Controller the user full manual control of the vehicle's vacuum actuated exhaust bypass valves. The controller has an integrated printed circuit board that controls the negative side of the exhaust bypass vacuum solenoids. The user can manually open the exhaust bypass valves to have that classic engine sound at all speeds and engine RPMs. Of course, you can return the operation of the exhaust valves to the car's ECU — which generally results in lower engine noise at low vehicle speeds and engine RPM.
The kit includes
The Forza Exhaust Bypass Valve Controller provides three different operational modes — all three modes can be selected using the included remote transmitter or a manual On/Off switch.
You can retrofit an existing Model B1 Controller to a Model B2 - Gaining all the functionality of the Model B2

Each kit is assembled using components designed to withstand the rigors of installation in the engine bay of a modern sports car. The enclosure is extruded aluminum. The internal circuit board will withstand the elevated temperatures that tend to exist in the engine bay of a vehicle. The connection cables are constructed using high serviceability TPE insulated cabling rated to 105° C. Connectors are weatherproof automotive connectors to resist moisture.
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.
Installation is straight forward. You only need to select a location to install the controller, unplug the vacuum solenoids, connect the included 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 controller includes one Remote Control Transmitter.
Additional transmitters are available.

The new model of the Exhaust Bypass Valve Controller includes indicator LEDs on the side panel to ensure correct electrical polarity of the connection cables.
Connection cables are assembled using high grade UL listed SJEEOW cables. These outer jackets and wire insulation is TPE insulation that is water and oil resistant and designed to withstand constant exposure to temperatures as high 105° C.
One remote control transmitter is included with the kit. Additional remotes are available for $10 each. Click here for additional details.
To help you install the controller module, we include some 3M Dual Lock Reclosable Fasteners. Dual Lock can be compared to Velcro ... but with a difference. Dual Lock provides very high tensile and sheer strength in temperatures up to 105° C. Applied correctly, it makes mounting of your controller easy and secure.
The kit is compatible with vehicles having exhaust bypass valves controlled by a vacuum solenoid. Some vehicles may have usage precautions, contact us for more information. Some vehicles may have differences in their electrical connectors to the vacuum solenoids, again contact us if you have any questions.
The following vehicles have been validated for compatibility:
Based upon known design parameters, the following vehicles should also be fully compatible. Contact us for the latest information or if you have any questions.
We are currently engaged in verifying functionality and compatibility for other vehicles. Please contact us if you do not see your vehicle in our compatibility listing.
The following table provides a full detailed description of the Forza Model B Controller.
There are other after market devices or controllers to manage the exhaust bypass valves on various motor cars. We believe that the Forza exhaust controllers are the best that is available and are superior to others.
The Forza unit is custom manufactured for the job and all components have been designed for long term reliability. It costs more to manufacture, but we are keeping our price very competitive to assure total satisfaction. The Forza unit is completely plug and play. It is ready to install out of the box and no modifications are required to install it on any vehicle.
The table below provides the full design details for the Forza Model B Exhaust Controller
Forza Model B Controller
Able to sustain high temperature conditions that are present in an engine bay.
Other controllers typically use ABS plastic that does not stand up to heat as well as aluminum
|Controller Module Configuration||Manual
switches located inside controller module
|Installation accessories included||Yes
|Max temperature recommended for installation location||105 °C
Higher temp has no effect on enclosure, but could affect internal components
|Control Cable Construction||
four conductor cable with high flex TPE insulation on wires and
cable jacket rated at 105 °C
Cable rated for hard-usage applications, water and oil resistant and other harsh environments.
Competitive products typicall utilize loose wires contained within a braided or coiled nylon sleeve. Protection from elements is minimal using this kind of wiring.
Both ends of cable fully protected from dust and moisture using Tyco / Amp weatherproof connectors.
Cable connectors fully protected and sealed using weatherproof boot
Compare to less expensive nylon connectors that are not water or dust proof.
|Antenna||High-gain 1/4 wave external antenna
An inexpensive dangling wire is frequenly used by competitive products. Although functional, a dangling wire could be prone to breaking and will not likely provide optimum reception.
|Option to use a manual On/Off switch||Yes
The Forza controllers are the only ones that provide the option to use either the included remote or a manual switch that you could install in the cabin.
|Always closed option||Yes
The Forza controller is the only one to offer an "Always Closed" option.
|Fail-safe mode to ECU control||Yes
|Number of Included Remote Transmitters||1
|Controller Kit Cost||The Forza controller sells for $375. Capristo sells their remote kit of lesser quality and function for $650. Novitec sells their Switchtronic system (similar to Capristo)
for $600 to $1200.
|Extra remote transmitter cost||The Forza remote sells for $10. Our competition sells their remotes for $20.
