Never tried that lol so idk. But sounds good in theory

Also if you have 1 cat. One side of the motor is gonna have resistance idk the symptoms

What if I replace the cat with a piece of pipe, then put the oxygen sensor in right next to the other one, behind the cat? So id have 1 cat with both oxygen sensors behind it, and 1 cat deleted with no oxygen sensor. Crazy, but I don’t see why it wouldn’t work. Thoughts?

Sounds like a lot of messing around IMO.

When I had no cats on my 97, I had put those spark plug non-fowlers on the O2 sensors and the cat codes never came on.

Why not just spend $140 on the y-pipe? It's 100% bolt on, doesn't leak, runs better, even sounds lil better.

This is going to sound wild, but hear me out. Right now I have that car held in with a steel can cut in half and expanded to fit inside both pipes covered in exhaust paste and wrapped in aluminum tape.

I hope you don't burn the truck down. Sorry but that's way beyond half-assed and I have my doubts about it staying together. I'm kinda funny about putting what could be combustible materials close to a smoking ass hot converter.

If you shoved a tube in there and welded it, ok, you might get by for a while.
