S8 Catalytic Convertors

[sutherland]

Does anyone here have experience of replacement cats for an Audi S8 02? I need one for bank 2 (nearside). Yes car parts (whoever they are) have them on ebay at £281.67 (item 180327439043). I haven't managed to get a price from Euro Car Parts yet.

I also went to a company that makes stainless steel exhausts. He talked about the possibility of fitting a high flow cat, but was concerned about the effect of having one standard and one high flow, but his price for two high flow cats wouldn't be much more than the price of one from someone else.

Any advice on the high flow cats or a source for cheaper replacements?
