Taking a closer look at it....
Federal manufacturing dates 10/95-12/98 had only two catalytic converters on the manifold.
California from 10/95 to 07/97 had only two catalytic convereters on the manifold. California models went to 4 total one year before the Federal versions did.
Mine is a Cali model, since it was originally sold to a gentleman in Apple Valley, CA. Build date is 10/95, though, so it only has 2 cats.
