Hi every1! i'm having a straight through stainless steel exhaust made from the manifolds to the back boxes, looking under the car today i noticed a pipe coming off each each side of the front pipes and travelling up into the gearbox area? anyone know what these 2 pipes are for? also is it ok to just disconnect the cat wires? help most appreciated.... :xxx: :bow:

those are from the AIV system and are used to help heat up the cats

They should be the pipes coming off from the AIV system. Just block them up and dump the whole AIV system too!
