These cars only have one bank for O2 sensors, so you can ignore the bank 1 part. If this wasn't happening before the header, it's pretty safe to rule out the MAF.
Are you getting all three codes back, or just the lean code?
Did you install the header, or have a shop do it? If it was done at a shop, I'd go back and ask them to check for leaks and to make sure both O2 sensors are plugged in and in the right locations.

Thanks for the response. I'm on UEL stg2 91oct OFT v2.068. And it only started after I took my car to nextmod to install it for me. I'm also now getting P0137. It's saying rear O2 sensor low voltage. Is it safe to drive the car and just erase the code for a bit? As well as is it normal to smell gas on full out catless exhaust?
