05 Corvette 02 sensor codes

[bnt performance]

P0030, p0036, p0050, p0056, p0135, p0141, p0155, p0161, all the codes have come up after putting bassani headers on it.. I did two cars back to back with the same setup and the other is not throwing any codes.. I know I can just delete them, but wanted to see if anyone has come across the same problem and what you did to solve.. thanks

Generally you have to turn off the rear 02 sensors when you install high flow cats or offroad pipes. The sensors go out of range with the higher air flow and think you've damaged the cats. Make sure you only turn off sensor 2 in both banks. It doesn't always come up right away, not sure why. Some cars can go several weeks and then the codes go off.
