Uh-oh! CEL after header install! Please help
Ok, I had my 4-1 headers installed today, and everything has gone fine. Drove all day with no problems, but on my way home from work the CEL light came on. It is driving fine, I think maybe it has something to do with the O2 sensors. I don't have any cat on it. Any ideas? Should I just disconnect the battery for a while to let everything reset...I never did that after the install.

disconnecting the battery will reset it for about 1 day, but as you're driving all of the sudden you will feel a small jump of the car and if you look you will once again see a CEL on...
YES YOU NEED to add a CAT, and your o2 sensors will have to be elongated, remember 1 before the cat, and 1 after the cat... good luck

Well, its kinda ghetto the way we did it. I just took off the flex pipe section and welded it on since there wouldn't be any mandrel bending for a reasonable price. Ok, so I guess it will drive fine without damaging anything right?
