Exhaust Rattle??, Need some help.. Can't figure out location.. Options

[bseaman_5]

Hey, I have a custom exhaust w a borla xr-1 muffler, exhaust is 2.5". I'm just getting really irritated w the annoying vibration I'm hearing, but its primarily when I GET on it.. At first I thought it was the cables in my trunk for the hatch lever, to pop the trunk. So I've done what I can to tighten that up so it can't rattle, I'm still debating on wrapping it with some sort of padding so I know that it isn't what is rattling. But to me when driving it sounds like its either the muffler or possibly the heat shield in the back where the muffler is?? Does anyone have this problem or have they experienced this problem??? Any ideas as to what to do to fix the problem? Could it be something inside my muffler or just a crappy muffler?? I'm debating on just replacing the muffler but I don't really wanna spend another 100+ on a muffler, if it fixed the problem great but I don't have that at the moment to just buy a new muffler. I've also tightened my liscence plate so I know that it's not that either.. Any help would be much appreciated..
B.
