After some searching I am still not sold on what to use. I see a lot of "weld a 22 (or 24, I forget) nut on your test pipes". There has to be something better than this, no? Just curious for those of you who have a wideband setup, what did you use for the bungs?
White wheels are getting painted silver this winter.
