I know a guy with hollow cats, has a Jeep that looks exactly like mine and it runs great.

Why would you disregard what the manual says? If it says it affects fuel/air ratio than it does. And it DOES. I was having an idle issue and had codes p0141 and p0161 and replaced both downstream sensors, and voila, no more idle issue. These hillbilly mechanics that "went to school" need to go back to school.

These work great. I have them on my Jeep and my S-10, only my sensor was too long so I had to use two and drill out the bottom of the top fouler. Worked like a champ.

How do these work, I would think by moving the O2 sensors into colder air and out of the exhaust stream they would think its cold out and increase richness by adding more gas? just curious

I have not had a magnaflow cat last more than two years before blowing chunks out the tailpipe.

I do not think the "air" reaching them is much "colder" if you use those spark plug non foulers on post cat O2s ... just less measured partikel stream per time unit. (as if the cat is still there)

And the air fuel mix gets mainly adjusted with help of the PRE cat O2s ... which you should not touch!

LOL

on my first jeep, the factory cat emptied itself into my muffler.
i put a new muffler on it. the empty cat was fine. never threw a code.
kinda sounded decent. had a welded thrush with the empty cat.

i have never heard of magnaflows failing?
seems to be the go to brand of hi flow cat.
the price is decent also. is there a better one out there?

YOur right seems to be the go to cat. Don't know what was up with the two
that I have had. There are other brands out there, but they cost quite a bit more money. Don't know if it makes a difference, but I did not get the tj bolt on cat, but the universal weld on unit.
