Thanks for the info Mike.  I'll have to see if this passes the inspection from the B.A.R.  I never really thought about the heat needed for the cats to work.  I was just trying to think of a way to get them to fit under the truck.  My motor is from a '04 taco which, has a pre-cat and a cat that I think is a bigger setup than yours.  I'm just trying to get everything to look and work like it should so it will pass inspection on the first try. 

Do you have any helpfull hints for wirring this thing?  I just got a '01 harness and ecu from a 2rz so I won't have to run a custom gas tank for evap purposes like Bevin.  This should make wirring a lot easier I hope. 

Also, I just picked up a IFS steering box at the junk yard durring my last spending spree for the future hysteer setup.
