I have to say, I'm with karri on this, possibly with a slight variation :

the flaps should stay such that at low revs all the air flows through the small ports and has good velocity and the correct resonance, but at higher revs rather than the air having to go down all four runners to get into one, if the roof was removed then it woulld have direct access. that combined with some nice radiusing (wouldnt bother fabbing bells for it, if you do that, build a whole new one) will make some sizable benefits indeed.
