If you follow the instructions, and follow the cycle of the SET valve when you turn the key on, you can figure out when it is open or closed.

Or, after you unplug/disable the servo motor, you can manually open/close the valve with pliers while the engine is running.

Open = louder, closed = quieter.

If you have an aftermarket full exhaust, your SET valve went away with the original exhaust into the corner of your garage. You will want to unplug the correct wire in the ECU to eliminate the flashing FI light, and get rid of the actuator cable, and the servo motor if you want.

Once you unhook the servo actuator cable, the SET valve will automatically snap OPEN and stay there.
