Bung for wideband

[Fubar]

I've got high flow cats coming tomorrow and i'm wanting to have my exhaust guy install a bung or 2 for wideband... My question is does the bung install before or after the cat, i had an 04 GTO and im thinking we installed it before the cat... And is there any certain angle the sensor has to sit ?

Definitely before the cats. I know there is quite a few write-ups on install angle and distance downstream, but most wind up putting them where possible.

Writeups - check the mfg website. I ran a PLX WB and I'm preety sure they had info available. www.plxdevices.com

Here is a manual for the NGK AFX and it has some infor on positioning. http://www.ngksparkplugs.com/pdf/AFX...ual_REV_06.pdf
