I’m about to order one but can someone explain the flap position, do you move it to the open position by hand and does it remain open, plus has anyone noticed any performance issues, as Ford claim the flap not only reduces noise but helps back pressure at certain speeds, think that’s bull but proof is in the pudding, it’s the extra noise in all modes I want, plus smoking from both pipes all the time, always looks crap on a cold morning when gases come from one only, thoughts please
