Default Check Engine light codes

Hello all, I'm posting a list of codes I have retrieved from my 00 corvette FRC. I recently had to replace the wiring harness to my IAT sensor and install a new IAT sensor as it seemed the wire was cut to it. I cleared the code for that and it ran fine without codes for a while until recently it threw another check engine light. I bought the car with long tube headers and I believe is catless, but not 100% sure. It had the loudmouth exhaust when I bought it and a god awful spoiler that I've since taken off and put on the stock mufflers I got for a really good price. Here's the list.
Selected brand: Chevrolet

============1==============
P00D9
Raw code: 00D9
ECU: 10
Status: Pending

============2==============
P2800
Raw code: 2800
ECU: 10
Status: Pending
OBDII: Transmission range (TR) sensor B - PRNDL input

============3==============
P0430
Raw code: 0430
ECU: 10
Status: Pending
OBDII: Catalytic converter system, bank 2 - efficiency below threshold

============4==============
P0420
Raw code: 0420
ECU: 10
Status: Pending
OBDII: Catalytic converter system, bank 1 - efficiency below threshold

============5==============
P0155
Raw code: 0155
ECU: 10
Status: Pending
OBDII: Heated oxygen sensor (HO2S) 1, bank 2, heater control - circuit malfunction

============6==============
P0430
Raw code: 0430
ECU: 10
Status: Confirmed
OBDII: Catalytic converter system, bank 2 - efficiency below threshold

============7==============
P0420
Raw code: 0420
ECU: 10
Status: Confirmed
OBDII: Catalytic converter system, bank 1 - efficiency below threshold

I appreciate any help you guys have with this. Hell, I guess it might need a tune?
edit: also, all FRCs are manual, including mine, so why do I have that transmission code?

You’ll have to get underneath the car and see what you have...the P0155 is pending so you’ll see what happens with that DTC !!

Hey, nice necro. I ended up talking to my buddies at East Coast Supercharging and got my ECM reflashed to get this light to come off. It's expecting a signal that It wasn't getting.
