3) shut down engine
4) start up
5) get out of the car as soon as possible
6) wait for the valve to open on the driver's side exhaust tip (you can hear this by an electronic mechanical noise OR by placing your hand at the exit of the exhaust tip and making sure the air is coming out OR visually by simply getting down on your knees and checking that the valve is open)
7) unplug the actuator from its plug that's connected to the left side of the exhaust (could take some time until you learn how to unplug it, you'll be relieved when you do!)
8) with duct tape, cover the tip of the actuator with at least 2 layers to avoid water to get in
9) hang the actuator to a fix surface using duct tape
10) enjoy a 5% increase in sound dB levels
