theres also been research done that proved the cat acutally did a lot of good for the performance of the engine etc... providing it was a hi-flow cat...
as for destroying it - i've killed one which had the ceramic centre - too many knocks on rocks and just general 4x4 vibrations made it fail... since replaced with the other type (platinum coated steel i think it is???) and no issues.
theyre also not really that expensive - and if the guy who's putting it in doesnt mind - you can ask him to weld it up so the cat is a clamp/bolt in replacement... not sure if its worth the hassle though - although one end of mine is like this to make removing the back end of the exhaust an easier job.

The worst thing about censorship is ███████.
Qld is the same if you car comes with one it's illegal to not have one or to gut them. Probably illegal to run around with damaged one too the way they are these days. You would only have one I would expect as the factories generally only put twins in high performance twin systems like V8's. Check the price of performance aftermarket cats they have come dowm considerably in price over recent years and flow well. Don't put a factory one back in you will most likely remortgage your house to afford one.
Probably throw engine codes too. This will lead the engine to run in "open loop" mode ("limp home") causing poor fuel consumption and poor performance.
The ceramic types can turn to dust from vibration and knocks, and be blown by exhaust gasses to block the remaining ceramic honeycomb near the outlet causing loss of performance (strangling the exhaust flow).
Regardless of the legalities, it just doesn't work to try to remove them permanently.

George Carlin, an American Comedian said; "Think of how stupid the average person is, and realise that half of them are stupider than that".
A commodore/walker cat is only ~$100 new. You can buy a lot of them for the cost of the fine. You can also see straight through them. As mentioned they have little or no resistance to flow.

Hi flow cats are a waste of money. Just buy/fit one that is standard for your exhaust system. All the hi flows do is allow more sound through. So unless you run a turbo and need to open the system right up, don't waste your money.
And yes the EPA fine is huge for removing the Catalytic Converter.

no worris thanks for the help ..... i do have 2 but if they arent that expensive i'll get new ones .... my mate got 2 for his xr8 and said they were 300 bucks each andi thought stuff that i'll just put a pipe in ....looks like he got ripped off hehe
new ones it is
and to superslowlux i got a 2.5inch with a strait threw mufler and it made a bit of difference in power mainly more responsive than actual power i'll se what happens with these new cats i get too

When I priced cats for a research project that was about the price $100ish for a commodore, $300+ for a falcon of the same vintage.peeko22 wrote:no worris thanks for the help ..... i do have 2 but if they arent that expensive i'll get new ones .... my mate got 2 for his xr8 and said they were 300 bucks each andi thought stuff that i'll just put a pipe in ....looks like he got ripped off hehe

If cats for your car are expensive, just find a cheaper one of the same size.
If the exhaust places want too much, you can buy them from repco or similar. The commo ones bolt in - so easy to DIY.
