Ok, Please stand corrected!
The Federal law is quiet specific.
It states that if you make ANY change to your vehicles performance, you must take the appropriate steps to ensure that the vehicle complies with the Australian Design Rules that apply to those modifications.
I'm paraphrasing there..
So, if you change your exhaust and it's louder than before, then you SHALL have it inspected and a noise
test performed. If the vehicle is contraviening that ADR that specifies the particular noise levels, then you will need an Engineering certificate!
If you add a roofrack, then it's a no-brainer, as the roof rack has been designed to a relevant ADR and therefore complies.
If you were changing your
suspension, you hit a
grey area, but if you fit a new engine, boom! Engineers certificate!
I did the ADR thing with the last car I seriously modified, my 1992 GT Falcon. It was a pain in the arse.
