Hi guys. I want to ask you a question. I have a 340i with the akrapovic exhaust system. A friend of mine has a 328 2012. He asked me to give him my stock exhaust. We made a quick experiment. 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?
