removed cat and got p0420

Hi there! Well... I was wondering how to bypass that code so I don't get that SES on my car? I know ZZP can tune my PCM or something like that... but if it all takes a o2 sim... where can I get one? Cheers!

You can get the 02 simulator/emulator at 3800performance.com. See link below.
