Cats,chptr.X: true?

Is this true? Been doing research and found this paragraph on another forum regarding the so called catalytic convertor on our pre '07 diesels:

"You need to do some research. IT IS NOT A CAT!!! It was not even possible until they took sulfur out of fuel because sulfur destroys the CAT. (they started to take sulfur out of gas in 73) Diesel got away without having CAT's because of the excuse that the sulfur in fuel prevented that. Starting in 08 you will see diesels with true CAT's on them (maybe of a few later 07's too) but not on any 06 or earlier because the high sulfur fuel then would render it inop. Some like yourself like to call them CAT but they are not. The are nothing more than thermal reactors to trap and consume particulates and nothing more but call them CAT's if it makes you happy but they are not."

Let's say this is true, does this mean the EPA "technically" couldn't fine you for not having a REAL cat...I mean you'd still be pumping out soot, which in itself is not good in the eyes of the EPA...but if it's not a REAL cat, then how can it be regulated by CAT law??? Guess you'd need a lawyer to argue this, huh? They'd prolly try to fine you anyway if you presented the Law with the above argument. Fascinating.

I could be wrong but I think he has his facts incorrect. You have to burn unleaded fuel for the cats to work not the removal of sulfur. Thats one of the reasons they went to unleaded gas was cars with catalytic converters.

It's easier to call that thing a CAT than what it really is.
