Just wondering why the O2 sensor was moved from the exhaust manifold to the catalytic converter.

My sister's 245's header pipe rusted out at the bracket welds, which probably adversely effected mileage, as the O2 sensor is after that, at the cat. Whereas, if the O2 sensor was on the exhaust manifold, mileage would probably have been maintained.
