I haven't had any luck finding those around my area (Orange, CA). I'll keep an eye on eBay and Craigslist.

Isn't there an obvious modification test to your smog test? Wouldn't a deviation side to side raise concerns? Will the ECU be able to compute the correct AFR with the imbalance? Lots of people have taken their exhausts off and they are just sitting around. Not to mention wrecking yards.

From my understanding, the ECU only use the upstream O2 sensors to calculate the AFR, so whatever downstream of that is for emissions purposes only. I've been driving the car for the past two months and couple thousand miles, it has not set the codes P0420 or P0430, but will not set the Catalyst monitor either. From what I've read, for my model year 2001, during a smog test, they don't measure the tailpipe anymore, just plug it in and read the Readiness monitors.
