O2 Sensor Location
 

Hi everyone, I recently bought a '94 FD, and the check engine light came on and after I flashed the check engine light and looked up the code it said my O2 sensor wasn't working. After looking in my car I'm pretty sure there isnt even an O2 sensor on it, being that it's not stock. Here are some pictures of my engine, all I need to know is where the O2 sensor should be located on my after stock engine. I have a small idea, but please tell me otherwise if you know better.

Here's the link to the pictures

Does anyone know if the highlighted area on my pictures are where the O2 sensor should go? Any information is appreciated.

yeah on single turbo setups they go onto the downpipe
is the car running currently? if it is, then they must have an o2 somewhere

The car is running alright, I think its running too rich though. I haven't seen another O2, I guess I will buy one with the wiring and then hook it up. If anyone knows of any good O2 sensors that come with the wiring please post. Thanks for the help NeedFD
