I don't know about break-in periods for the cat.. anyone have any experience on this? I did Drive the car around for about half an hour before the test. The cat however was put on the day before so don't know if that would make a difference.

Hmm.. two cats on a pipe.. yea, I'm sure it'll help a bit, but not crazy about going through all that only to fail again. I'm going to try to do a tune up on my car I guess before the next smog.. maybe even retard the timing.. heard that helps.. dunno. I've been to only about one 240 meet so far, pretty new to the SF area.. I'm going to try to be there saturday @ union city though.
