o2 Sensors where are they?

[eclipsegst3131]

hey, i'm looking at getting a 3" downpipe (eliminates the cat as well) for my 2g gst and i just want to know where all of the sensors on the exhaust are. i know there would be one on the manifold and the o2 housing. but is there any anywhere else? please let me know asap. thanks

there is one going into the o2 housing and one right after cat in exhaust. look under your car right near where the door handle is, directly under that underneath car on exhaust you should see that sensor there. There is a total of 2 o2 sensors.

there's one on the manifold as well right. the o2 after the cat is on the catback portion right and not the downpipe?

If you have one on your manifold it's an EGT sensor ( to monitor exhaust temp.), like stated above there are only two, one on the o2 housing and one after the cat... not on the downpipe.
