the vec-c air intake pipe fits the vec-b (between TB and airbox) or as pottsey says, go for a silicone air intake for a larger bore pipe, as for the cold air feed to your box, your better off running a new one down to behind your grill! i also like the k&n panel filters, some will say they do nothing but each to there own.
deff do the pre-cat.
polish & port your TB, get rid of you egr as this is putting hot gases into the TB (which carn't be good) good cat-back exhaust, 2.5" if you can find one!
and thats about all your cheapish smaller stuff!
hope it helps you mate!
