I've got a fullsized 4-2-1 manifold though. You can buy decat pipes though I'm not sure where from, any exhaust place should be able to make you one easily enough though!

You won't need a MIL eliminator/O2 cheater as yours is a pre-facelift which only has 1 lambda sensor. If you buy a decat pipe and it's got a second hole you'll either need to plug it with a suitable bolt or do what I did and get a lambda sensor from a scrappy and screw that in there (cut the cable off it so it's worthless and you'll get it dirt cheap). If you get one made obviously this won't be an issue
