Depending on where you're at around here though, depends on wether or not they know that seems like.
Hollow out your cat, and push it out somewhere behind the cab and you should be good.
Yes there is too Tom, in all emission testing counties. They test everything under 10,500 lbs GVR, so Superduties are exempt. They plug in and test the OBD2 on 03 and up and they smoke test on 02 and earlier. They even have a new attachment now so they can smoke test trucks with stacks.
I removed the cat, then just took the heat shield that goes between the cat & the floorboard and welded it upside-down. Now when he looks under the truck with the mirror, he sees the shield & thinks it is the cat.
