I just got a 95 S6 a few weeks ago, and it presently has a stock exhaust
system on it (but only till it's air tested). Then the gutted cats go back on.
They almost passed, missing the NOX standard by 2 points. The EM is not stock
however, as it has an RS2 manifold and turbo.
If this would help let me know.
