MIL eliminators are no longer legal in the US (technically they never were). All the companies that were manufacturing and distributing have been shut down.
My advice, keep your cats. They are not restricting your performance significantly, and if you really want more performance, get some high flow converters.
Gutted cats are horrible for performance, they act as an expansion chamber which kills the exhaust velocity and as a result the torque, and they act as a restriction and that kills the top end too.
Besides, who wants a truck that smells like a burning gas station?

Ok well then i would like to cut them off, and my truck is at about 160k miles and i think the cats are startin to become clogged, and im 16 an in highschool, which means i dont have alot of money, itd be easier to just buy a mil eliminator and cut off the cats than buy new cats, i remember seeing them pretty cheap, alot cheaper than new cats.

there are no negative affects that i've felt other than the Check Engine light if you don't have the eliminators. personally, seat of the pants tells me that my truck is a little perky, but i have no proof.

Ditto. Not sure what the MIL things cost, but you can get high flow cats ofr like $60. Also look into WHY the cats are plugged. Cats are not that bad. Franky a good high flow cat with a good size inlet/outles dia, will flow all that 4.6L needs. How loud do you want the truck? You already have streight pipes. How much attention do you want from the cops??? How much damange to the reputation of 4wheelers do you want to do?

Well being that the only thing the MIL eliminator does, is allow you to loose the downstreem O2 that tell the computer that the cat is working. It still does not fix the problem of WHY the cat went bad. Or if the cat is just coming off to increase flow/noise, there is much better ways to do it.
