ok so my car didnt come with stock exhaust..its basically the stock exhaust of another car on mine..also a 97z has 2 o2 sesors..mine doesnt have any WTF..nor does it have a hole for it after the cat..so what i wanna do is make 2 holes with the right thread pattern and install the sensors...how much is this gonna cost me and can i even do this..also just to be sure ..the plug is AFTER the cat right? and the first one is somewhere on the downpipe?

Shouldn't the Check Engine light come on?

it is on..its been on since the day i got it..never bothered checkin it out..car runs alot better than i thought it would..no o2 sensor and all..

just buy a simulator to put behind the cat, and put a regular one before the cat.
that would be the way to go IMO.

actually, if you did that ^^^^^ you wouldn't have to have a cat on there.
