Are you saying that 2.5 inches CAT-BACK ( single) and 2.5 inch headers are going to restrict my top end with a non street ported engine??? And is the Street header considered long or short??? I think anything will give better top end than my stupid stock muffler dont you think?

No. 2.5" is fine for any n/a unless youre running LOTS of nitrous. And the street header is short primary.
