Well I have had my headers on since Tuesday, and driven over 150mi, Just trying to get it to throw the code. But nothing! Should I worry about this or just leave it be until I am ready to tune.

It shouldn't be a problem. I didn't have a code pop up after a few days of driving either. Do you think the headers are giving you any more power without the tune. I really didn't think I got power gains until I got my tune on the car. But my butt dyno doesn't seem to be as sensitive as others'.

I can definitely feel more top end power. Low end is basically the same. But the sound it makes is amazing lol.

it'll be fine until you get a tune, but the CEL is coming. Dont worry.
