Where are the oxygen sensors located on a 2002 Acura RSX Type S?

The sensors are located on the catalytic converter. There are two of em; one closer to the downpipe and the other in the middle driver side of the cat. They are a pain to get off with the heat shield in the way. Best tool to use is a 22mm open ended heavy wrench. *Do not replace with universal o2 sensors* I know oe sensors are expensive, but you're just gonna have to bite the cost. Universal sensors do not work.
