I would imagine that the check engine light is on due to the O2 sensor picking up that my secondary cat isn't there. With that being said is there anywhere around Morgantown, WV that I can get my car tuned? I don't have the knowledge to do that stuff and would prefer to do it here rather than making another trip home. If you have any other suggestions let me know. Thanks.

No, the ecu only monitors the cat in header, the secondary cat is not monitored.
see Basic Bolt on Mods Guide link below.
The CEL light is likely due to the aftermarket CAI throwing of the MAF sensor scaling or if it has oiled filter, oil on MAF sensor.
This will result in codes such as Air Fuel imbalance or rich/lean codes due to fuel trims maxing out.
Or you have intake air leak or installed intake incorrectly
But you really need to get a odb scanner and read the CEL code from ECU to be sure.
