Got a Service Engine Soon Light today

[crayzitalian3]

on my way to school this morning i saw that my SES light came on. so later on in the day i got it checked out and the code was P2423, and the autozone guy printed out the receipt with the possible problems

here are the results I received:-HCAC System Bank-Failed HC Absorb Catalyst-Air leak in exhaust system-Failed heated oxygen sensor - Bank 1 Sensor 2-Failed heated oxygen sensor - Bank 1 Sensor 3

Now the first thing that came to my mind when I read this was my headers and the possibility of one of the o2 sensors crapping out on me.

honestly im not sure what the problem is and I have no idea what to do.

any ideas guys?

just curious have you had your headers for a while or just recently? cuz on my stillen headers ive noticed that theres an exhaust leak rite where the bolts connect onto the engine. my ses also came on when i noticed the exhaust leak. on the top of the headers it looks like i have 2 small black spots due to the exhaust leak it needs to get welded.
