I recently hacked off my catalytic converter assuming, correctly I think, that I could just shut off the code with hpt. See up in upstate NY, when it gets this cold out, they don't do emissions testing, they just check to see if you've got an SES light and if not, you're good. I just wanted to know if it really is as simple as just turning the Catalyst test off or if I'm missing somethnig, before I load the tune.
