not to complain about something but I'm a little concerned...

I installed a testpipe a few days ago and still have not gotten a CEL light... does this ever happen? Or is my CEL light broken...?

where does you o2 sensor mounted on the straight pipe or on the little pipe on the side of your straight pipe

You have to meet the test criteria. For the rear O2 it is something like X miles at steady speed. Depending on your driving it could be days or months.

The CEL should illuminate everytime you start the car. If it doesn't the bulb is out.

How long have you owned the car? Maybe the rear o2 was disabled?

i actually just installed invidia dp and test pipe and i bought the extender for the o2 sensor so it doesnt throw codes and its fine.. i also have a scangauge hooked up so i would of known if the code was on.. from what i heard the o2 sensor on the test pipe doesnt really throw codes but dont take my word for it.

yeah it says "service engine soon" when i turn on the car... prev owner must have had the rear o2 disabled?

Service engine soon every time you start the car up? One thing you can count on when buying a used "stock" EVO is that it wasn't always stock". Good luck, sorry I am of no help.

but if the rear o2 was disabled would the car have passed smog?
