I believe it's there for the same reason your exhaust resonater is there, to reduce sound. You could use a plastic connecter to fill the gap (something like the one that connects the vaccum line to the accordian-style tube on the intake). Otherwise just head down to your local hardware store and get some 3/4"(I think) hose. There's really no point in eliminating it unless you need to.
