whats up im new to this forum so bear with me please

i purchased an 07 cobalt SS and it already had the catless striaght pipes installed.
i recently installed the gm stage 2 kit and due to bad mechanics my computer was reset to default settings and i lost the software for the catless pipes so i now have a check engine light that MUST go away for me to pass inspection which is very soon .. can some one please tell me what i can do ?

you are going to have to go to a tuner and tell him u just want the 02 sensor malfunction code wiped out.... should only cost like 30 bucks.
