By removing the expansion chamber, the engine still physically has access to the same amount of air(didn't change the size of the intake or intake tube diameter), but removing the chamber actually makes it harder for the air to get into the engine because of destructive interference with the resonant frequencies that are no longer dampened by the chamber. I'm not sure how much of the chamber was for performance versus for US intake noise regulation however...
