You dont leave it closed, you pull/close it only when you need to quieten the exhaust some when let's say, you're driving next to a cop. You want it popped open since it chokes up the exhaust. It makes a big difference on my RB25 with ISIS blast pipes. Didn't make much difference on my SR20 with Buddy Club IIs. With it closed, the car is slow and feels like dog shit.
