But it is beginning to look like that is what will be required to keep the yellow light out and the cruise control turned on. Did I hear someone say something about pre obd??? Sounding pretty good right about now.

I have heard good things about Walker brand CATs, an OEM supplier without the OEM markup. Something to look into. Its also really easy to determine if the CAT has lit. Grab a temperature gun and check the temperature before and after the CAT, it should go UP at the back, preferably by a few hundred degrees F.
