Bad Lt1 Camaro

I got my new magnaflow exhaust put in today, new y pipe, took both cats out and put pipes in their place, im going to get it tuned on the dyno in a few days to delete the o2 codes but i drove all day and the check engine lights didnt even come on! I could have bet my life that would have tripped some sensor so is something not working right? im not mad cuz the ses light didnt come on but i think its abnormal that it didnt. just seeing what u guys thought ....oh and it sounds great lol

It will come on for the rear O2's... but OBDII takes three trips to see the same fault before it sets a MIL light.... it's not three KEY cycles.... it's actually three starts, warm up, etc., etc.....
