Default RennKat and they seem expensive to me 600 bucks...but i guess that what happens when you go...
performance on an Audi your gonna pay. EVOMS offers RennKat. Its worth it if you've opened up the flow from in to out. then its worth it.

Default I have a Random Tech cat in my 99.5 Looking to go back to a stock cat.
I have the newer version random tech cat, and it does occasionally throw CEL codes.

A good replacement but not really an upgrade. Still flanges down to 1.9"
