Some of the earlier federal 2000 models like mine (originally from Iowa)and yours only have 2 cats. All the CALIF models in 2k and those after a certain production date ? came with 4 cats including all of 01-04's.

I would love to have some CA smog legal headers like those that JBA offers for the new models. I just replaced my passenger side manifold and if the other side goes I may looking into modifying some pathy that fit the VG30

Thorley makes a CA smog legal set for the VG30 and I’ve been told with some work they can be made to fit the VG33.
