Remove cats... but not emissions legal!!

Or put a cutout on it.

i was thinkin about it ...my Cats cap on the passenger side rattles is that normal in this Gen?

Cutting cats will make it sound hella loud but it wont pass a smog

I don't think Ive ever owned a vehicle that would pass emissions, usually the first thing i do is pull the cats off and scrap them. im looking forward to doing that on my expedition seeing that there is 4

I replaced my cats(four) for two Magnaflow High flow Cats. Oxygen sensor were retained fore and aft of the cats so it still passes emmissions and does not give a check engine light/code.

I know on the mustangs they make mil eliminator modules to fool the check engine light when you remove the cats. Do they make anything cheap for ours like that? vs having to buy a programmer or custom tune them out.
Doing this offroad of course

idk...but it depends where the o2 is if it throws the CEL or not
