If you want it loud......keep the mufflers you have and add a off-road H-pipe. THat will really wake it up. Hell my brother had NO mufflers on his 96 GT when he still had the stock H-pipe and it STILL wasn't very loud

h pipe
 

i was just hoping to stick with the stock h pipe due to warranty and stuff b/c my car is a 2002. i dont want to have to worry about spending money each time i go to the dealer to take off the new h pipe and putting the old one back on, pain in the neck, believe me though, i know a friend who has a h pipe and i love the sound and wish i could do it my car, thats why i was just looking into the 1 chamber flows or dynomax racing bullets

I sorry dude......your prob. not gonna get the sound you want. My brother had NO mufflers on his GT and it still wasn't THAT loud.
