rear, your car is testing what the o2 level is coming out of the cats, so when you take your cats off... you put the mils in and those bad boys tell your car eh, **** looks good.

If the light comes on get it read to make sure it is throwing and O2 code and not something else.

Do you have an exhaust leak? Might want to tighten up the bolts to make sure that isn't causing the problem.

the drivers side bolt dosnt connet to the header tight enough...so there is a little leak

...and that's probably why you are getting the check engine light/code. Gotta fix that leak - try loosening the bolts and adjusting it back together again.
