[W126 Coupe] Catalytic Converter questions

[Iain Gunn]

Actually they barely pass WITH cats, and even if they did they would fail on 
No2 (Nox) As far as I know a cat is the only thing that will remove.

So without cats these cars won't pass an emissions test? I thought they 
burned clean enough that they could barely get by without cats.

It will improve performance and I would wager longevity of your
engine.  Was your Euro federalized when it came over?  Regardless, my
SEL felt great sans cats.  I hollowed out each so it would look
correct for a visual inspection.  As long as you don't have emissions
testing you should be fine!
