When adding a Whipple Supercharger are the headers and x-pipe a must or will it be fine with stock manifolds and just a cat-back exhaust???

Catalytic converters (namely cheap after market cats) don't hold up to bad tunes that aren't designed to protect them(and exhaust valves). Not really because of airflow.
You'll make more power with aftermarket O/R exhaust. But that has draw backs also.
