no need - unless the pipe is completely rusted out and one step away from leaking.

well i don't know where u got 2 sensors for under $50, but the best Denso I can see is the one above, only one rear, for $150 US ... and what's with 3-wire and 4-wire? i take it that i should get sensors with the connector attached right? seeing them for sale without a connector scares me because they look like a permanent invitation for me to do some soldering ... so which is it? 3-wire or 4-wire ??????

It depends on which of the 3 o2 sensors you mean (i think you were talking about the rear one. Some of them have 3 or 4 wires.

You can look up your old o2 sensors and count how many wires they have - i am guessing it should be either 3 or 4. There is not a whole lot of difference between them - 4 wire type just has an extra wire for signal ground (in addition to 2 heater wires, 1 signal wire). The universal (cheap) sensors come with crimp on connectors - so no soldering is necessary - you just have to cut the sensor off from your old connector and crimp in the new one (after figuring out the wire colors).

Just to add my 2 cents, I had codes from both of my o2 sensors.I suspected bad plugs and wires so I changed them, cleared the codes, and they never came back. Bad plugs were causing my o2 sensors to give an inversion error. I would suggest that before you spend a lot of bread on something you may not need, clear the codes and see if they come back. If they do come back, you may find that a rich or lean condition (in my case rich) may be causing the codes and not the sensors themselves. Just my thought on the matter.
