It is always considered by almost everyone, without question, bad for the environment to delete your cat. You aren't even supposed to ask for tips on the subject on here. But, maybe so cut and dry. This link http://keelynet.com/biology/cfs.htm isn't proof of course, but may be good evidence worth looking into that cutting off your cat mat be betterbetter for the environment. Just throwing this out there since no one ever questions the merits of a catalytic converter and, of course, everything should be questioned.

that said, I do have a cat, just bought a new one actually but not for environmental, or legal reasons (I don't have emissions testing where I live, I can just renew registration by mail or online, and a cop will NEVER look under your vehical for a catalytic converter)

I don't have any on my vehicles, and it's no longer against the rules to talk about it.

It's not against the rules here anymore, but may not be "legal" depending on location...but there's also one reason to have it.
That's how it was designed, and keeping it that way is simple in the long run.

Most fuel injected engines cycle back and forth between rich burn and lean burn to control both NOx and CO. A lean burn produces nitrous oxides and a rich burn produces carbon monoxide. In order to reduce both contaminates, the engine is designed to cycle back and forth in fractions of a second. This is where a closed-loop system with O2 sensors is necessary for maximum performance and fuel mileage. If any part of this system is eliminated or changed, performance will suffer. The best thing you can do is install a high flow cat to reduce restrictions.

Platinum hasn't been used in converters in quite a while because of it's cost, being replaced by palladium and rhodium. The older cats are worth a lot of money and converter theft was commonplace.

Only the front o2 sensor affects you air/fuel ratio, the rear is only there to monitor the cat and trip a code.
