We placed (not installed) the 340 muffler and connected only the actuator. He put sport + but the valve didn't open. I believe that without the gas pressure it can't open but I am not sure. What do you think?
It's electronic, it doesn't need any pressure, however, some people have reported that the valve doesn't open without a slight tap of the throttle.
