Default check engine light after header install
Anyone experience a check engine light after header install. I had cats installed, and emission fittings. Just cleared the codes but I'm sure they'll be coming back.

You need to get the car tuned for the headers.

What was the codes? Did you write them down? If not, when they come up again post them.
