Hello,

If I decide to buy the Kooks LT Headers with high flow cats or cat less will I be able to run them without requiring a tune right away or is the tune an immediate thing?

Keep it low rpms (no wot) and get a tune as soon as possible and you will be fine.
Did it with mine. No tune for a week and daily drove it. Buddy did it with his camaro ss as well.

What he said ^, you’ll be fine under partial throttle. Definitely wouldn’t go WOT though to be safe. If you’re moving more air (headers) without adding more fuel , you’ll be leaning out under WOT. Probably not enough to do damage, but why take a chance. Just get it tuned a soon as possible.
