The catalytic converter has nothing to do with rich or lean.  Look elsewhere.
What are the symptoms?  Codes?  Limp mode?  Are you using a wideband to monitor?

Well I can't find anything obvious as to why my UrS4 is running so rich. Is
it possible that my catalytic converter is fried from some great track days
last fall?
It's a newer generation Stromung system, installed about 35k miles ago.
Full(er) RS2 goodies CRB 6 speed - where 3rd gear did most of the track work
for me.
Already replaced O2, plugs, boots, temp sensor, oil. If so, where does one
find the right replacement cat?
