Question for car people….

I currently live in QLD and about to move to NSW. I have heard that it’s a bit more strict when it comes to roady worthy (¿pink slip) regarding emissions and noise.

My question is, if my car has an aftermarket invidia exhaust system, do the cops really care if I’m not hooning around and is it still “road worthy”?

Follow up question. Is it worth changing to a valved exhaust or back to stock?

Thanks in advance!
