From what I have seen on various cars (4AGE powered cars that is) the exhaust will mostly just give you an increase in noise (a little more top end if you get a good exhaust system but not really noticeable on the road). The cast exhaust manifold on 4AGE's is meant to be quite good anyway so extractors give very little benefit.
The extra exhaust noise will definitely give the illusion of a faster car though.
