Default Trouble Codes Question.

I have an 02 Z06. It has Kooks long tubes and a Blackwing filter on it. The check engine light just came on and it's throwing three codes:
P0420, P0430, & P1415. I'm pretty sure these are emissions. My question is, does it mean I need new 02 sensors or new catalytic converters, or both. Any help would be appreciated. My inspection goes out this month so I need to get it fixed quick.
Thanks

Did you look up the codes? Sounds like your secondary AIR injection system is failing.

Thanks. I went to Autozone and had them plug it in to give me the info I'm giving.
The code receipt the gave me said :
P1415= AIR SYSTEM BANK 1 fault
P0430=CATALYST EFFICIENCY LOW-bank 2
P0420=CATALYST EFFICIENCY LOW-bank 1
Thanks for the info so far. Any help is appreciated. I'm trying to not spend much money getting it diagnosed right now since I'm spending all my money for Christmas for my boys.
Thanks again!

A lot of people with headers just have those codes tuned off by a tuner.
You will not notice anything different except no service lights.

I'm all for that, but I don't know if it will pass TX state inspection.

If you have it tuned out, it will. If it's just a stuck check valve though, it'll be faster and cheaper to fix that.
