Just what Killer said. NPP exhaust valve.

So I just found the forza controller that allows the driver to control the valve. Anyone have one of these?

Yes, I have the 2 mode one ( factory mode or always open) E1 is marked on the controller and has a 2 button fob. There's also a 3 mode one (factory mode, always open, always closed) E2 is marked on the controller and has 4 button fob. Which one do you have?

Like others said it's the exhaust valve for your NPP exhaust. In other words it's the volume control for your exhaust.

I have a manual 3-way switch wired in so I can go always open, always closed, or normal operation.

Same as factory mode between 1,000- 3,000 rpm when the exhaust flaps are kept closed

I have the 3 way Forza and it works. Open, closed or factory settings. I leave early and always close the valve. Its is still a bit loud till it idles down after than its pretty quiet. The car will start with the bypass open and will not close until you get to about 20 MPH or for me around 2 gear. If you get on it it will open. I leave it open all the time but close for starting in the morning. If I have the back seat down to hold my fishing rods and am on a long trip sometimes I will close it. Its worth getting and the instructions on installing it are spot on.

I would be looking at the manual version so I could leave it closed for cold start. Starting in the underground garage is like putting an amplifier on an already super loud exhaust. I love my NPP and want to keep it. I also don’t want all of my neighbors in the apartment to complain to management about me.

I am afraid of wiring the system without the forza, not any level of electrician here and I am pretty sure I would get something crossed.

The location of the toggle switch is awesome and definitely doing that!
