Default Difference between a bad O2 sensor and exhuast?

I keep throwing a CEL, and Im assuming that its because of the headers, but Im not sure. When I installed my headers my O2 sensor was stripped, it took me like 15 minutes to just get it out. Now when I first intalled the s-pipe I put on an anti fouler and the CEL stayed off for a long time. Then it came back on, so I reset my ECU and it stayed off for about 1400 miles then came back on. So I reset it again and it stayed onle for about 500 Miles. Im going to go to orielys today to check whats making the CEL come on.

Whats the code for a bad CEL and what the code for the CEL being thrown for the headers? And is ther any chance the anti fouler just might not be a good one and could I get a different one and it work?

Yo tcduck I told you it wasnt going to work, I was the one you a had an exchange with if the CEL bothers you take off the header. I had my AW header for over 15,000 miles my CEL didnt come on untill I drove the first 250 miles. I had no change in MPG which was my biggest concern. But the change in HP was bad ___. THe only way to fix the light is to remove the header. I never thought of doing that,ill keep the horsepower over a little CEL. So far so good in my experiance. INJEN CAI ,INJEN AXELBACK ,INVIDIA S-PIPE ,STIFFY ETD ,HEAT WRAPED ALPHAWERKS HEADER, 55 SHOT ZEX = Alot of phuckin fun.

There are still plenty of people on here who have never thrown the CEL. I know I dont want to drive around with it on constantly 1. I dont want to see the light 2. there could be another problem and not notice and 3. I know we can fix it. but we'll see.

If it were that simple it would have been fixed already, RIGHT??? But it aint .Todays ECU is complex dont mess with it cuz it will figure it out before you do. Thats why i said if you dont want CEL put it back to stock setting. I aint trying to phuk with you in no way. So leave the header on if you want the horsepower other than that leave CEL on after all you know why it is on. No disrespect but you be happy with the power gain.

IT SAYS vvt-i on the valve cover in dumb $hit terms it means variable valve timing with intelligence. So the computer on the on board ECU wont take no $hit, It is to smart.No phucking around with it . The ECU knows your driving habits. The ECU is so smart that it even knows if you dont warm up the engine on a cold morning, No lies just the truth. Why would i say this, to make you feel bad. No, to help you out.
