Redwarf Posted August 13, 2008 Report Share Posted August 13, 2008 What engine is it going on? If your car came with a cat, it's illegal to remove it. Quote Link to comment Share on other sites More sharing options...

MYSTIK[RL] Posted August 13, 2008 Report Share Posted August 13, 2008 4afe its getting done at a exhaust place so its legit doesn't mean its legal, may want to ring up your local authorities and actually ask, I'm sure they'll tell you the consequences, which if i remember correctly are along the lines of a fine up to $10,000 and the possibility of time in jail Quote Link to comment Share on other sites More sharing options...

Redwarf Posted August 14, 2008 Report Share Posted August 14, 2008 If your car came with a cat, it's illegal to remove it. Refer previous comment. You'll get picked up for it on your next pink slip or green slip inspection. (whatever they call it in NSW) Quote Link to comment Share on other sites More sharing options...

Johno Posted August 15, 2008 Report Share Posted August 15, 2008 When i got my 2 inch exhaust they rang me half way through the job because my cat was too old. I said just leave it but my exhaust place said they can't do it cos it's illegal. Had to fit a new one, no way around it they said. Quote Link to comment Share on other sites More sharing options...
