Induction kits!!

[hicks_22]

i want to buy a K&N induction kit, ive used them before and love them, but on my corsa it has that pipe from the exhaust manifold going into the airbox and a flap with a sensor. (for when its cold starting i guess) can i just remove this and put the K&N cone on? will it damage vaccuum?
cheers

that pipe messed all my engine up with a cone filter on.... might do same to urs but also it might not
