hey mate i have a 34 with a hole that was cut to make way for the intercooler on my car , ive been defected for this as well , Paul Xtreme motorsports on compton road cleared my defect of course for a small fee , however i do know Scott from SMP performance can get you one as well , My piping hole is under the battery and it isnt a defect i would suggest you get on to one of these guys or any other reputable mech and get it sorted out
