Pods fine here in QLD as long as its secured down, not flapping about. Mate of mine is getting his car looked over has front mount, high mount turbo, pod, waste gate. Just has stock suspension put in wheels with good tread (borrowed my 9.5 rears and 9 fronts. ) and they let him through fine. Only hold up is that he doesnt have a engine number lol.
You will only have to change it if they tell you to but as long as its secure then it should be fine.
