Jez 0 Posted November 26, 2008 Hi, just a quick one if anyone can help, do you know whether a cat from any audi S3 (1999-2004) are interchangable? Only mines collapsed and I need a new one and need to know which ones I can go for second hand. Cheers for any help you can give, mines a y reg 210bhp car incidentally.
