Well the titles pretty much state what i want but i want some performance with it not just sound i orginally wanted to run True Duals but i dont know now because of cleance under the car so yea im really want a site that offer sound clips or something i still perfer true over others but yea im mostly looking for performace and sound emission crap doesnt matter no emission law were i live haha XD so you think you all could help me out?

 

im trying to make mine sound meaner as well. right now all i have is a flowmasters exhaust system. my future plans are longtube headers, offroad y-pipe, and an lt4 hot cam. and im pretty sure its guna sound pretty nasty and on top of that.... more horsepower. i dont know much about working on cars, but i do know thats some of the main things u can do for sound and horsepower.
