Not strictly true, the empty box will act as an expansion chamber, slowing the gas velocity and therefore increasing back pressure. But it'll still be an improvement.
TBH go to your local exhaust place and ask if they have a bit of pipe you can have, then just cut the whole box out and weld the pipe in instead.
