CEL's come on when the car is detecting a fault, usually emissions related. the light did not come on because the o2 sensor wasn't faulting at the time, though it will store the code in the computer so you can't pass emissions inspections. it will probably happen again though the next time the o2 sensor can't adjust enough to the a/f ratio you have going on in the pipes. a tune will help with this, but also, you can have them turn specific codes off in the computer so it won't come on regardless while tuning usually, that may be your best bet
