Hey guys I tried some searching on google and the forums and I have not come up with much information. Those of you that are running a wideband af gauge where are you installing the 02 sensor? I wanted to get some ideas on setups before I weld a bung in this Downpipe.

The Focus ST has a wideband from the factory, the O2 sensor closest to the turbo. I would imagine that the Fiesta ST is the same, which is why a wideband does not seem to be a necessity for e-Tunes on these cars the way it is on other vehicles. This is only an educated guess on my part (as is the case with most of my posts)

EDIT: it is not the rear, it is the front that is a factory wideband.

Gotcha. I realized afterward that your question was specifically where to weld in the downpipe bung and that my answer probably wasn't helpful. ;)
