    Not normally they can be tiny not sure of spelling , the noise u mite be hearing is a loose or missing blanking plug for a sencor or a loose fit either end, if it's got a dpf the pipe mite have come off they whistle if not fitted rite. Good luck

    If it's the Tdci the cat to manifold dose not need a gasket  but you have to make sure the three nuts tighten down evenly then hand tite the two bolts on the can that holds it to gearbox then the two bolts last  that connect to the middle section then once it feels set tighten the bolts on the cat to gearbox plate .
