New exhaust...O2 sensor location after cat? Need help ASAP
I am having a new exhaust put in my 3.4L swap (96 3.4L M/T 4x4) and the exhaust shop said that the after cat O2 sensor needs to be exactly on per the manufacturers spec. They have the truck right now and need this information this morning first thing!
Where does the rear most cat need be located?? (So many inches, mm, etc after the cat baffeling).
Also can I use regular style round hole O2 sensor bungs in place of the stock Toyota style studded mount? Does Denso sell this style o2 sensor for the Toyota??
Thanks,

You should use the stud style and not the threaded bung for mounting your O2 or you may not be able to the correct sensor to fit your vehicle. If it were my truck I'd do the studed type even if it was a bit more work.

ok new question.
For the studded style O2 sensor bungs. I have one that I got with the engine which is located before the cat and another from my original 94 exhaust system. Can I use these two existing bungs in my new system? Because I have read this morning somewhere that the physical sizes are different for the before and after cat o2 sensors and might not fit. Can anyone confirm this?
