my 99 2000 and 2003 didn't have one from the factory.....

 

neither did anyone else's 99, 2000, or 2003... because they didn't come with them from the factory.

94-98 12v trucks did come with them from the factory, and it is against federal law to remove them. Most states don't care, but if the inspector goes by the book and knows which trucks had them and which didn't, he'll nail you on it.

nothing fishy about it, it's a factory installed piece of emissions equipment, and it's required to be in place

 

Exactly.......Thats what my reply was too....

 

which is false...

89-93 had no cat, 94-98 12v had a cat, 98.4- early '04 had no cat, 04.5+ have cats
