I just picked up a slightly used GS V2 downpipe. The previous owner was using a clamp on thermo coupler after the first o2.



Whats everyones opinon on the best method of plugging it? Should I just have it welded shut?

I was considering just tapping the hole and threading a bolt into it. But obviously the stainless is very thin. Don't know how long that would last.

That's what I was thinking about the wideband. But Nick told me to put it down by the oil pan. And I recall reading somewhere that it's suppose to not be close to the turbo.

I suppose I could just get a small stainless bung welded on though, as you suggested.
