What am I looking at ?????
The other day I had my 2005 Ranger Edge 4.0 4X4 up on a rack and was looking at the exhaust and I could tell what I was looking at. Off of each header pipe was a canister that looks like a cat. converter then when it goes to single exhaust their is another canister that looks like the other two, then the muffler. Am I looking at resonator's, cat converter's? Do I really need all of that backpressure?

pretty sure its cats cats cats and more cats, fords are notorious pollutors, so from factory they just added more cats, you can replace them with one larger one (if avail) to cut down on the cost of buying all those little *******s.

Removing all the cats and just installing one is against emission laws. Laws state the same number as factory, and in the factory locations.
oralP- I have not looked under a V6 Ranger in awhile, but I would guess you have pre-cats on each bank, then the main cat after that. The pre-cats by far are the most restrictive on most vehicles.

that must be a cali law, in canada its as long as you can pass emissions its legal, no matter how many (or few there are). Im replacing the pair on my 2.9 with a big-bodied walker. should have no problems.
as for the ford polluting problems, thats why there are so many cats. shouldnt need more than one if its o.k. im not that familiar with the 4.0, but even the 2.9 needs 2 never mind a v-8

You got me about Canada laws. I have no idea about them.
So many newer vehicles run so clean using computers and other new technology (better oils, fuels, 1486345345 sensors that monitor EVERYTHING) that cats are really not needed. Its just that they are required by law. You could supertune most carb'ed engines to pass all but the most stringent of emissions tests.
IMO, most factories use them for cold starts, thats when the worst polluting is done. Kind of hard to get around that with just tuning.
