Finally getting my o2 bung welded into my downpipe. Any recommendations as to where to put the bung? I read that it should be at least 34" from the turbo, but then I read that the further away the less accurate the readings will be. I was thinking of putting it towards the end of the downpipe by the second o2 sensor. Any thoughts? Anybody else weld a o2 bung onto their downpipe for a wideband?
