JCMF has it in one regarding WA but I have not heard what Lance has said applying over here, but that does not mean that is not true.
Any car originally sold after Jan 1 1986 must have a cat convertor.
If you want to get your car over the pits and the engine takes unleaded fuel, its my advice from my actual experience, to fit a cat convertor.
If you are like me, with a pre-1986 car and a post-1986 engine, and the rules could be interpreted to read that cars before 1986 don't need a cat, regardless of the year of the engine, you are in muddy waters with the inspectors and the Police. Its a small issue not worth the hassle and argument with the cops. More below.
If you care for the environment you will run a cat.
If you want the best of all worlds, get your local muffer shop to fit a second hand cat they have pulled off a car recently, with a flange at either end, into your exhaust system.
After you are passed, unbolt the thing, knock out its internals and re-fit it, or replace it with a resonator to keep the noise at a similar level, or just get a straight through pipe fitted there. This way, by using flanges, you can always go back to what is 100% legal when/if you need to, without replacing large sections of your exhaust system.
