Wideband Bung

I am about to install my bung and i have been looking around on placement. I am installing headers as well that have catless connection pipes. Just got my headers freshly ceramic coated and don't want to weld in a bung on them if i don't have to. I've read put it before the cat because after the cat can make your readings off but since I am catless could I just put in right into the catless connection pipe?

I would go behind. So if you wanted to pull the wideband and install the rear o2s someday you just weld in one more bung on the other side

Lessons were learned. First time needing to do a wideband.

you only need the bung if your going to be installing a gauge. if your getting a dyno tune they will remove your narrow band o2s and use those holes.
