My 2018 has 140k and the converters are starting to act up and throw codes. It is affecting performance. Instead of replacing I’m going get rid of them and turn off the o2. Any thought? Thanks.

How are you going to delete the rear O2 sensors? I know most tuners won't do it, but maybe you can do it yourself?

It’s a novelty at first, but quickly wears off.

I would keep them on just for the smell alone. I was happy when I swapped out the off-road X pipe on my mustang for a catted X pipe. My garage and clothes no longer stunk.

SUCH a terrible idea. No respectable tuner will tune them out, and like it was said above it gets old. These also sound TERRIBLE with out cats or a muffler.

As @LokiWolf stated, I've spent thousands of $$$ and hours of work trying to get rid of the awful sound once I mucked with mine. I'm pretty good with it now during normal use, but my recent towing trip was pretty terrible!

I know someone with tuning equipment
Remember, this has ZERO to do with local laws. To remove CATS is a FEDERAL offense, and the EPA is taking it VERY serious now. Again, no tuner worth their salt will tune an onroad vehicle for no Cats. It just isn't worth the possible fines, and has almost zero performance gain over a quality aftermarket downpipe with aftermarket cats.

Again, begs the question why these cat thefts are so "victim-less" and considered not that important. they should be felonies and treated as such. Guaranteed if I removed mine on my own, and got caught I'd get in trouble.

How many catylitic converters are on the 3.5EB engine? I have the impression there are four (4) and doubt they'd all be bad. One (1) of mine is and is waiting a replacement under warranty.

Just putting test pipes (wink, nudge) in the exhaust won't cure any latent engine issues anyway. My '17 needs a cat but Ford says they're on back order. I looked briefly at a aftermarket system and there was a warning that the cats would be destroyed quickly after installation if there were existing engine problems. I was just curious as my system is still under the Federal warranty and I have no driveability issues just the annoying light on the dashboard which I turned off knowing the problem is still there.

There are two. And they’re probably not bad (I.e. they’re probably doing fine in terms of reducing emissions.) I am coming to the conclusion that Ford has developed an overly sensitive emissions system—from what I have read and now personally observed.
