On a somewhat related note.. I wonder what GM's reasoning was with putting an un-monitored cat downstream from the monitored cat. They must be using it to reduce how much pollution they are rating the camaro at for federal regulations, but by being un-monitored, the emissions tests are only going to give them what the first set of cats are outputting anyway since nobody uses the sniffer test anymore cept obd1 cars. Just seems to me that both should be monitored if you're not gonna sniff test.

I'm suspecting it has to do with exhaust flow
could be wrong, but it's surely possible.
Remember when mishimoto did the testing and found out that the crimped pipes near the rear have no effect on performance?
The second cats, along with pollution reduction, could have something to do with exhaust flow.
Think how lava flows in lava tubes, first.
The same principle can be applies to ANY form of matter, even gasses. If you keep something Hot, it flows faster and more efficient. The minute it cools down, relatively, it becomes more dense and moves slower.
I think they also mentioned something about em, and beating a guzzler tax or emissions deal on the v8s with that design too.
