So what is more deadly, the old leaded fuel or the new fangled unleaded fuel that has a whole lot of other carcinogens?The cats are only there to reduce emissions, nothing else. Not create back pressure or any other fairy tale.
If it is illegal where you live, then it's totally up to you whether you run that risk or not. Here in Australia it is illegal to remove cats if they were fitted from factory. The reason we have cats in the first place is because pre cat emissions killed all the unicorns. Pretty sure all the people that have either removed their cats or smashed the guts out have made the Western Black Rhino extinct as well.
Removing cats is illegal in NZ? A mate has recently got his 07 SS tuned and one of the first things the tune shop did was to remove his cats. I'm getting my 04 SS tuned at another tuner and they say they want to remove my cats as well.Fairly sure that too is now illegal here for too.
edit:Hahaha Deuce beat me to it.
Yes, a catalytic converter would be a restriction in an exhaust system, just like a muffler. The question is how much of a restriction is is? Modern cats, like a good quality muffler would be a minimal restriction. Running an open exhaust (when tuned for it) will produce more power than a muffled exhaust system, this is fact. However on a street driven car, do you really need that last 1.5% of available power?Not sure why everyone is ripping the dude. Yeah he may be trolling, but would be good to get a genuine answer for future searches by other new members.
It is for vehicles after a certain build date. A couple of years ago the Government changed the emissions laws, they set a specific date/year and only vehicle post that date can be imported now. Fairly sure the same legislation also stipulates that it's illegal to tamper/remove emission control systems on those vehicles.Removing cats is illegal in NZ?

mate, most factory cats BARELY scrape through the emissions tests we put them through for approval. some have even had to have additional cats fitted. those BS "high flow" cats would never pass in a million years.That brings me to high flow catalytic converters, how many would actually meet emissions standard? Fairly sure many don't,
