Can anyone confirm that all '99's had a precat in the exhaust manifold? I was under the impression that was essentially the difference in a cali car and a 49 state car. I'm gonna be hella unhappy if I go to the trouble of pulling the manifold out for nothing.

 

Probably not worth much, but IIRC, cali cars have 3 O2 sensors and non cali cars had 2. I'll look up the pre cat **** real quick...
