I need to get cats fitted to my S600 for it's first UK (The car had striaght through pipes fitted when I lived in Dubai), and it's seems the best price is from cats Direct, which is a very reasonable 350 inc vat for the pair, although that is for the cermic ones. Does anybody have any experience with cats direct? are there any other options for reasonably priced cats? I was quoted nearly 3,000 gbp by the main dealer in Dubai, but haven't checked any Uk dealers since I got back. Having never had to replace cats before, I have no idea whether it's false economy to get the cheaper ones, or whether the metal ones are a better option than the cheaper cermics etc. Anybody have any thoughts on which route to go, or other companies selling potentially better cats?
