Header/X-Pipe/Exhaust Combination from Stock

Hey Fellas,

First post - 1995 Triple Black 5.0 GT Vert - 113 K - plan on starting the performance mods this summer - runs like it has 50 K - great upkeep. Had these in mind to start - goal is 300 HP within the next year or two plus major body enhancements: (Exhaust has to be replaced first, is ancient and pathetic)

Summer 04'

Mac Cold Air Intake (Purchased)
Headers (Suggestions?)
Bassani X-Pipe
Borla Exhaust

Body (To start)
Cervini Stalker front piece
Saleen Sport Tonneau Cover
CDC Light Bar
Xenon Back piece
Full body detailing

Looking for suggestions for the best/most powerful header/x-pipe/exhaust combination - open to anything right now - real basic mods in my mind to start off with - if anyone has any other suggestions to start off with in addition please feel free to add - also anyone with the same make/model feel free to add your thoughts on starting off almost all stock and beginning your mod's.
 
Long tubes are actually quite a bit quiter than shorties at idle and while crusing. I don't know about WOT. I was suprised at how quite my setup (LT, prochamber, MAC cat-back) was at idle. But that's with stock heads and cam. I'm sure it'll be different in a month...:D
