Alright just like the title says i am in need of O2 sensors for my longtubes and i want some advice on which to run. Ive heard negative things about the vette rear o2's and ive also heard negative things about stock replacement o2's with extensions. Im just looking for opinions here.

Don't get new sensors. Re-pin your computer to use the rear O2 harness for the front sensors. There is a good write up on this site for doing it. It takes maybe 20 minutes and cost ZERO.

I went with the bosch 13111 o2 sensors(vette rear o2's) instead of extensions. They've been working fine. Wish I would have knew I could have just re-pinned the computer.

So if im reading this correctly i could repin my pcm and this is just a cheaper alternative to buying new sensors? Also ive heard from people on here that the bosch 13111 sensors are harder to tune. Is this true?

Just repin the PCM. It does literally take 20 minutes. Your rear sensor plugs will now be the fronts. No extensions or long anything to deal with.

13111's work good for me.
