Its supposed to close at higher rpms in closed loop operation (not WOT)... But everyone seems to have conflicting reports... I can honestly say driving around right now sounds like I have a REAL mild exhaust not loud at all, just a little more grunt starting off from stop etc.

Not just idle or whatever in anycase, who cares. its like a 5 second mod, if you dont want to do it, dont.
