Is the installation of the controller plug-and-play?
Yes. Each controller is provided with all the necessary electrical connectivity accessories. There is no wiring modifications required on your vehicles. No wire cutting. No wire splicing. And, if you ever decide to remove the controller, the car is exactly as it was before you installed the controller.
How does the controller obtain its power?
The Model B4, Model B4A and Model E3 get power from the vacuum solenoid connector.
The car’s connector provides the power through one of the two
pins on the cable. The Model B4-FP, B5, B6, E1 and E2 the power is obtained from a fused circuit on the car.
A fuse tap is provided with the kit to make this connection.
In each case, all parts required for establishing the electrical connection are provided in the controller kit. And, as stated above, there are no wiring modifications on your vehicle. Everything is plug-and-play
Where are the vacuum solenoid valves located on the car?
The position of the vacuum solenoid valves varies depending on the car. You can visit the
Supplemental Information page and look for your vehicle. Most of the vehicles
listed have a corresponding diagram showing the location of the vacuum solenoid valves. As more information becomes available,
this list will be updated.
If your vehicle's solenoid valve position is not in the table, check the vehicle specific installation tips documents or contact us with any questions.
How difficult is it to install? Is this a DIY project?
On some vehicles the installation is simple. If you
are handy with a wrench and screwdriver, it should not be difficult. A lift or means of raising the vehicle up is useful in some
instances. E.g., the Alfa Romeo Giulia is an easy install,
but you will need to gain access under the rear of car.
In the most extreme examples, the rear bumper may need to be removed. This is generally not difficult, but for the novice can be a daunting task.
Many customers elect to have a shop perform the install. Any competent auto shop should be up to the task. Also, reputable car audio system installation shops can be a good source.

Should I order the extra extension cable with my kit?
The extra extension cable is offered so you can extend the reach of the included connection cables. This extension is not an absolute requirement, but can be useful with the Ferrari 458 and 488. Click this link for more details, Extension Cable Details.
Will using the controller cause a Check Engine Light or log a trouble code in the car's ECU?
It should not. We make every effort to ensure that the controller is fully compatible with the vehicle. If a trouble code is known to be caused, we remove that vehicle from our compatibility list until a fix is implemented.
Where can I buy Forza products?
Will the controller void the new car warranty?
In the US, there is a Federal statute know as the Magnuson
Moss Warranty Act enacted in 1975. In accordance with that act,
a manufacturer cannot void a warranty because the consumer
installs an aftermarket part unless the manufacturer can demonstrate that
the installation of that part caused damage to another part that
is covered under warranty.

Using the Forza controller should not have any negative effect on any other component on the car. That said, if you have doubts, remove the controller prior to submitting the car for warranty repair. Once the controller is removed, there will be no evidence that it was ever installed.
What is the return and warranty policy for the exhaust controller?
You can return the controller for a full refund of your purchase price within 15 days of receipt. Contact us prior to return.
All controllers are warranted for 12 months. Should the controller fail, contact us for replacement or repair.
Is there a battery drain when you install the controller?
The only potential for battery drain is on the Camaro Generation 5 (model years 2010 to 2015). The controller for the Camaro
obtains power from the car's fuse box. The fuse box in the luggage compartment of the Camaro Gen5 (model years 2010 - 2015) is
always active. I.e., when you shut off the ignition, the fuse panel is still energized. However, with the Camaro Gen5, solutions
are described in the
installation instructions to isolate the controller from active power when you shut off the ignition.
You can read more about parasitic battery drain here.
For all other vehicles, there is no battery drain.
Are there written instructions or videos to help with installation?
Yes. Each controller kit contains printed installation instructions. You can also view/download instructions
There are some videos available for viewing. Links to videos are located here.
In addition, there are links to other vehicle specific installation tips and illustrations of the vacuum solenoid positions here.
Can I program the remote to the car's HomeLink system?
Yes ... if the car's HomeLink system is 2014 or later. Refer to your car's owner manual for instructions on programming the HomeLink. Click here for generic HomeLink programming instructions.
What are the options and alternatives to using the remote fob?
You can program the remote fob to your car's HomeLink system if the HomeLink system is 2014 or later.
You can also use a manual switch in place of the remote. Instructions for configuring a manual switch for the controller are included in the installation document(s). You can use a 2-way switch (On/Off) for toggling between Normal and Open. A 3-way switch (On/Off/On) is required for toggling between Open, Normal and Closed.
Forza sells an inexpensive and attractive LED illuminated push-button switch available on our Catalog page.
Can the controller be used on different vehicles or is it set to use on only one car?
Depending on the controller model, you may be able to use it on a different vehicle besides the one you first installed it on. Check the Compatibility Page and the installation instructions that came with your controller. You can access the installation instructions here. If you have any questions, please contact us.
Can the controller by programmed to open the valves when first starting the vehicle?
Using the Model B Series controllers, if using the remote, you can choose if you want the valves to be open or in the normal mode (typically closed) at engine
start. The Model E Series do not offer this option. At engine start, the valves will be in the normal mode.
With any controller, if you are using a manual switch, the position that the switch is in will dictate the controller mode. Because a manual switch is a mechanical device, the position of the switch is not reset when you turn off the ignition. Upon restarting the car, the controller will assume the mode that the switch is set for.
Do you have a list of resellers and service providers?
