    Yep no worries :) EGR doesn't go to the decat pipes though, thats the AIVs ;)

    What do they do then

    They were put there to get the cats up to temp faster. Basically inject air into the exhaust just before the cats and the ecu put a bit of extra fuel in. The fuel then burnt in the cats and got them up to temperature quicker :) Get rid of EGR and the AIV without any worries :)
