Holley hooker black heart question

I just bought a ‘99 Camaro SS convertible 6 speed. Planning an exhaust mod and I have decided to go with cat delete, hooker headers and black heart dual exhaust. I’ve watched countless videos but I have a question/concern I have not seen addressed. If I remove the air pump from the system as well as delete the cats, will any of this cause a check engine light? Wasn’t sure how the O2 sensors would react being installed essentially in a straight pipe. Also, will any type of tuning be required after this mod? Also, if anyone has any ideas or suggestions before I start please feel free to share 😊 Thanks!

Yes, deleting the cats will cause a service engine light. And yes, tuning can delete the light.

Yes, tuning in general will be needed to get the most benefit out of the LT headers.
