Basically, I know with petrol cars, a cat is law after 1993, but I was wondering, if the same law applies to Diesel?
I have a 1999 2.0 Di Estate and I'm on the quest for more power, and the thought keeps coming to mind...
Do I need a cat? If I don't I'm thinking of replacing it, with just a decat pipe, and replace the backbox to a free-flowing one.. (unsure what make yet)
If I can get rid of the cat, then I'll be happy, if not, are there any "sports" ones that you can get for diesels?
