That must be why my catalyst was NR. Either way, I'm not complaining.

SCT cannot turn off the "ready" settings when things are turned off for some reason , you would think there would be a way to turn it off to the point that the PC doesnt even look for it to be on when the tune has it turned off , Cant have it all lol

Oh, right. I always forget about that post 2003 part. I have the F2 header, as well.

I will eventually be getting a tune since i'll be running the SVT header, 2.5" orp, 2.5" flex and new exhaust. Just gotta get everything except the header. Have that already. Was glad to see Harris county just plugs into your OBD port when i passed mine in april.

you're in Cali, and i hear that place sucks for emissions. you'd probably have to reinstall the stock manicat every time.

I've been passing for years with no cat. Just recently I passed again with even more mods, complete EGR delete and such. I think that the computer saying it's ready is what passes it. If it did turn the ready off then it would fail the car. So SCT kinda did us a favor no?

Has long as they can plug something in and my car tells them "yeah I'm emissions compliant" then I'm happy. It's when they start shoving a sniffer up the tail, then I'll get worried. Or if the inspectors ever really know what a focus is supposed to look like under the hood.
