What lambda spacers are people using?

[Bob94]

What length/brand are people using? I've just fitted some lambda spacers tonight (pic below) and 20miles later eml came on :/ I'm running stock gutted cats. Is anyone else running stock gutted or have most got aftermarket de cats/test pipes

Personally, from my experience of using lambda spacers, they did diddly squat! So i wouldn't bother. as you have now experienced , they don't work. Your only solution is a re-map. Roughly £400.
