Ticking sound
I was putting my car away this afternoon and I heard a ticking sound when it idles. it's easier to hear if you're right next to the car but not so much when ur in front with the hood open. You can hear it pretty good if you get down and look under the car where the headers collect. It starts up about ten seconds after the car starts. what could cause this? could it develop into anything serious?

To me an exhaust leak is more of a tapping sound - ticking sounds electrical. Loose plug/wire/something arcing on the header....

How long after the headers install did it start ticking?

my first thought would be an exhaust leak from the way you describe it. An exhaust leak will sometimes make a ticking sound that sounds like someone pecking on metal with a screwdriver or something like that. If it's less noticeable with the hood up but more pronounced from under the car I would look at the exhaust first. What kind of exhaust clamps did you use and are the headers slip fit or flanged?
