I am not understanding. The part numbers of the 49 state and the CA version are exactly the same. Also, there are numerous threads on this site confirming that the only differences between CA and federal versions of the VX are the O2 sensor, the ECU, and the wiring harness. Therefore the original poster could have replaced with a used exhaust manifold from anywhere in the country. Or not?
