New Stang Owner Needs info!

Hey guy's i just Bought a 96 GT 4.6 5-speed last week and its my first SN94-up car and i always bashed on fords because i really like old Mopar musclecars but I LOVE THIS CAR! it is fun as hell to drive and has a Awesome sound anyway i bought the car and it currently has 116,000 miles on it someone had installed a H-pipe back Flowmaster exhaust system and it has the K&N filter (who doesent have that! lol) and a set of MSD 8.5 Wires and a strut tower brace, And this past Tuesday i ordered a Steeda Tri-AX shifter for it but havent recieved it yet. I bought the car straight out cash and have another car i will be selling soon and am looking into Buying a Supercharger for it and a Off-road X-pipe. My question for you all is Who makes the Best Supercharger and This isnt my daily driver so How loud would the car be with the Off-road X-pipe be with the Flowmasters, And how roughly how many HP would the combo listed above be. The car is black w/Lemans stripes so everybody wants to race (of course!) but i don't like losing! So what else can i do to get my New (to me!) Pony pissed! Thanks Dave Hughes :D
 
i have headers o/r x-pipe, and flow masters, and it sounds good, real nice sound when crusing, doesnt drone to bad like people say, and sounds wonderful when going through the gears. to be honest i dont know about the hp gain. i think you will be happy w/ flows if u get that o/r x. and i personaly like vortech superchargers.
