Catalytic Converter (Cali VS. FED) Options

[barterj]

I need a new front Catalytic converter for my car. Its a 2.2L and is cali. emissions. Is there any difference in the front catalytic converter for a cali emissions cat. and a FED emissions cat.?

if by front, you me the cat attached to the manifold, then no, the cali spec cat has an opening for an O2 sensor that the federal model dont have (pre '96) but, the actual cat itself is the same, you can just plug the hole.

So your saying if we get a new cat we wont need the o2 sensor after it ? (In all other states besides cali)
