Check engine light came on because of catalytic converter which I do not have.
Question is, this morning going to work it started flashing what does that mean? Is it going to blow? Lol

It means because you have bypassed the converter in your system either the last O2 is missing as well or it is reading it is gone. So it will continue to flash until a new converter is put on the vehicle. You can scan for codes and see if another code is coming on but it is probably because of the missing part. Your fuel mileage will suffer.
