the most important bit is the collector and downpipe.. it needs to be larger, 2.5 at least, 3 inch preferable, this should then run into at least 2.5 and then you can taper down when moving away from the exhaust to a free flowing 2 inch (minimum) as the gas pressure will have dropped considerably as it moves away from the exhaust.. i would want to be at least 2.5 to where the cat was orignally however..
ideally, 2.5/3 inch all the way through with no restrictions like a cat!
Mild steel decats from hoffman are fine.... the only real issue is the mild steel backboxes as they dont usually get hot enough to deal with the condensation and water..
hoffman decat, with a stainless cat-back (or from where the cat is/was) will be fine.
have a look on yell, or the like.. quite often there will be a little performance place that will do the pipework for you for a lot less than longlife, and it will be exactly to your specifications.

I'll go for a 2.5" system then, I'm looking for a de car, only one I can find is the Hoffman which is mild steel, anyone know where I could source a stainless steel de cat?

Given the choice between Niall and the sheep. I would choose the sheep!
