So last night I put my headers on and thought I was going to dodge a bullet with not seeing an engine light come on but it did today I won't have my diagnostic till Friday anyone want to give me a heads up into what I'm looking at till Friday

Either immediately or eventually, the CEL will come up after installing headers with tuning. What kind of heads up are you looking for?

Headers throw off the O2 sensors perimeters. Most turn off the second set behind the cats and other than tuning for performance that should be the only cell affected.

It will be P015B and P015D. It won't hurt anything, but you'll have to turn them off in the tune.
These apply to the FRONT O2's, not the rear.

My bad, I stand corrected. On my car the rear 02's were deleted. Must but specific to my TT Kit.

P015B & D is a code for the front sensors because of "lazy or slow response". These codes are not harmful and are turned off in the tune. With stock manifolds, it indicates a bad sensor most likely. it is a normal code to appear after header install that a tuner can rectify with ease.
