800 miles with no mil, and have yet to shut off the o2's with my tuner... but i was wondering the same thing when is the cel gonna come on?

well as of now minehas not come on yet and I did this post last year. but from what I have learned this is not normal. I am thinking about getting them in case that it does come on later. there are not that much anyway.

The ECM only test this system after so many drive cycles....and a drive is very complex and long...has met certian parameters....in order to test the rear cat efficiency .eventually it will test and fail...and then turn the cel on...

I put an O/R hpipe on my wifes car about a month ago and the light never came on. I tuned it off only because I was allready changing other things.

just a note my check engine light never turned on, I put about 25K miles on it and did the PI swap plus LT's to 3" X before it came on but I need to get it dyno tuned anyways for the new motor so I'll have them turn it off at that time.
