Hi peeps, been a while! Sold the A4 about a year ago now, was tidying out the shed today and found the OEM cat. I removed it back in the day and fitted a Milltek HFC.. It has less than 60k on it.. Was from a 1998 A4 so only single O2 bung.. I know that these have been known to break off at the flange area and can also suffer from collapsing.. Mine is free from both these problems.. I want rid, and it seemed to good to just dump.. Make me an offer. Cheers, Dan.
