What o2 sensors do I need?

[cmills26]

I have a 95 Cobra and want to change my o2 sensors. Do I have 2 or 4. I am thinking that I need 2 of them. I have a off road h-pipe and flowmaster 2 chamber exhaust. Do I need to change the ones by the headers or the ones further back? Anyone have any infor for me?

95 and prior have 2. they're by the headers.

The reason why I ask is that I went to Autozone and it showed for a 95 5.0 that there are ones before the cats and ones after the cats. So which ones do I buy? The ones before the cats or the ones after the cats?
