Just an FYI, the 02 spacer trick is to erradicate code P0420 only (cat efficiency) for those wanting to run a test pipe, or for those who's cat-converter has worn out and are tired of the CEL 
It has worked great for me on 00-05, but the 06-07 is definitely tough. It is very sensitive, seems like those who've had success are getting the luck of the draw, or very specific parts.
I have just tried:
-first spacer screwed into test pipe, untouched
-second spacer drilled barely bigger than the 02 for a close seal
the CEL still comes back.
At this point I am going to weld the hole shut in the first spacer, and re-drill it out about 1/8" maybe smaller.
I'll let you know how it goes....

My $$$$ is on no easy mechanical simulator for the DBW cars. The Catalyst and 02 sensor monitors are more complex than previous cars.
I've got a guy at work with a Berk TP and a 07 complete with CEL.
