Service engine soon light?
I just recently installed long tube headers and y-pipe on my car. And now the service engine soon light is on. Is this common??

Yes, especially if you deleted the cats - did you keep the AIR and EGR? Get the codes read free at some place like auto zone and post them.

did you get O2 sims? Did you put the O2 extensions in? Tune it at all? Pretty easy one to fix... probably forgot a combination of these...
