Default Check Engine Light from New H-Pipe

Hello, I am new to the forum. It is a great site, and I pick up a lot of good information. I recently purchased a bone stock 1993 LX convertible (Triple Black) and have made some minor mods after reading these forums. Besides a Flowmaster Cat-Back I upraded to a BBK Catted H-pipe. Here lies the problem. After the pipe was installed, my check engine light comes on after about 15 minutes. It appears to come on after the car gets up to operating temperature. Any ideas on what causes this? I installed a CAI, 73MM MAF, and FMS 65MM TB before I put on the H-pipe and never had a problem. Can any of the experts help me? Thanks.

I'm also going to guess it's something with the sensors.

if you did plug in o2's then often times when removing old ones if they were siezed in place the sudden jarring motion of breaking them loose damages porcelien portion inside....first item after all visual checks yield nothing would be to run a koer test and pull codes

The 02 sensors are in and connected. Although the simplest solution is usually the correct one; it doesn't seem to be that way this time. I'll check the sensors for damage, and get the code checked. With the exception of AdderMk2, I appreciate the help.
