Sort of ironic how so many ecomodders have converted to fed to help save the planet but are actually polluting it all to hell because they didn't transplant the full system, but just the fuel economy bits.

I appreciate you chiming in here! It is ironic indeed and I hope to put an end to it.
I wasn't aware there are different CATs. I can only find 18160-P07-A00. Do you know of the part number for CA emissions?
This post from a guy that seems know what he's talking about (I love guys that seem to know what they're talking about) says that there is no physical difference between CA and Fed VX CATs

Please help prove to the contrary 'cause I'd love to get this damn thing figured out and get back to the Fed equipment with those beautiful mpgs.
Thanks!
