I had a mechanic raise the car up, he thought it failed because my car is lowered and I scraped on it too much. There was quite a few scartch marks on it, but but I have never hit it hard. I always go over bumps real slow and rarely does it ever bottom out. If this is the case though I will just remove the cat and put it back on when smog time comes around. $350 for installed cat vs 50-100 for installation and removal every 2 years... Depends on how the O2 sensor is. olpus let us know how your experiment goes, sound interesting.
