so, its just a 02 sensor everyone is having? not a a/f? is dat right?

Actaully not everyone is getting a CEL. In fact majority of people dont have the problem. It seems that in most cases, the ones who are gettign CELs seem to find out they also have a damaged O2 sensor which likely happened during the install, This is not true for all of them but it is true in a lot of cases. Ive been running the Alphawerks with the antifouler mod for a few months with no CEL ever.

Heres a how to on header install along with the anti fouler trick:

The anti-fouler trick is "ALMOST" always successful in getting rid of the CEL... for some random reason, some people have problems with it, but many believe it's cause they damaged their O2 Sensor....

I'd say you run a 90% chance of fixing your cel problem with the antifouler on any header if you follow instructions on how to do it.

i had the alphawerks with 1 anti fouler installed and got the CEL after about 800 miles..everyone told me i needed 2 anti foulers so i ran it with 2 anti foulers installed and still got the CEL, only it came on quicker....i thought it might be a damaged o2 sensor as The Instigator stated it might be, but after switching it back to the stock exhaust manifold everything works fine and i haven't seen a CEL in over 3000 miles which i tend to think rules out the damaged o2 sensor theory

I have the Megan Racing header with the ZPI s-pipe and antifouler with no CEL, I have driven about 10K miles with it on and no problems.
