I have a 94 LS with DC 4-1 Headers and Straight pipe with 5 zigen catback piping. everytime i drive, around certain RPM's, i hear a rattling sound underneath my car, i have no idea what it is and it sounds so cheap. It didnt always rattling this loud until i keep scraping my piping over bumps and hills cuz my car is too dropped to manuever over any of them, or my piping may be hanging too low or off a hanger..

 

Uhh why don't you go under your car and look for yourself. May as well be a heatshield under there.

Yep that's what it probably is. I had the same problem. After scraping the heat shield around the crack a couple of times, where the screws are rusted around one of them and snapped free. I couldn't take it off because all of the bolts would strip when I put a socket around it. So I just bent the metal around itself so it had no room to vibrate.
