Default Will I get a check engine light?

I ordered Kooks headers and x-pipe with hi-flow cats that will be mated with Corsa Xtremes. No CAI yet. When I install a CAI, I will probably do a tune. Right now, adding the headers and x-pipe, will I get a check engine light untill I do a tune?

Probably not for a while. Get a tune as soon as you can though. Best tune after headers & cai.

I did immediately, & then it was intermittent for a while, but it's been on since. Other mods: vararam, spacer, & flowmasters, which have been on the car for at least a year together w/ no CEL. Getting a cam & tune next week, but I knew it may happen, so didn't sweat it. If that's all you're going to do (headers & CAI) do it all at once, if you get a CEL get a tune sooner than later.

From hi-flow cats maybe...But just get the diablo tuner. You can use it to store a custom tune as well. Worked fine for me no CEL.

Thanks, everyone. Looks like the consensus is a 50 - 50 chance of getting a check engine light.

LG LT street pros, and a Vararam for me. Light came on about the 4th time I drove the car.
Getting a tune as soon as the weather breaks

Tommy technical here -- my reading of this forum says it is almost a certainty you will get a CEL with your mods if you don't get it tuned.

The only real variable seems to be when. It would really suck if you got it on your way to having an OBD-II type emissions inspection...

Soooo, the moral is get it tuned and be done with that CEL....
