Default How to clean out chambered muffler?

I have a Flowmaster 80 series muffler (yes I know it sucks....) Anyways, there is a piece of metal or something that is rattling around inside of it and I need to get it out. The angles inside and funky design make it a bitch. I tried water, no luck. It still has the pipes on it too, and dont want to cut them off. I'm afraid it's going to rattle when on the car. Thanks!

Throw it away, and buy a magnaflow muffler that corresponds with the same size, weld it in and you got no more rattles and a muffler that wont rob power.

I'm thinking that it would be a waste to remove that one piece and install the muffler. If it has already started to fall apart on the inside. I'm sure that once that piece is out, and the muffler is on the car. More of it will continue to break off and rattle even worse.

Time for a new muffler.

The muffler isn't broke, there is a small piece of metal from griding that went in.

Maybe you could fish it out with a magnet but I doubt it.

Install it, maybe it'll get blown out.

Who knows, just seems like a lot of trouble to keep a crappy muffler.

I spent a coule minutes tonight shaking it and got a rythm going so I got most of the junk out. I don't feel like spending anymore money on exhaust parts, plus there are pipes already welded to the muffler to save install costs. I love the mufflers sound, yes it flows like crap but thats what the dual cutouts are for.
