3 way catalytic converter

[Zeinheiger]

Not sure if this has been covered before but I did a search and couldn't seem to find my answer. I apologize if it has been covered.

Would it be illegal to remove the 3rd/final stage cat converter? I plan to remove the resonator and was wondering if I could de-cat it as well? Legally... What type of sensors are involved in the last cat?

As far as I've read, for a car to be legal/roadworthy, "it must have A working catalytic converter" if I remove the final one. It still technically would have a working catalytic converter?

It has been discussed before, but in this case it is understandable that you didn't find the answer. Basically, it is still illegal if you remove it. Even though you have 3 of them, the car was designed and tested with all three in place. Removing one of them, even though the emissions may still be lower than the standard required in Australia, will still be higher than the tested design.

It would also be illegal to remove the innards from your cat to make it a straight through pipe that just looks like a cat from the outside. ;)

Just sayin'
