    Rattling when coming to a stop

    When I come to a stop I usually hit the clutch and put it in neutral then brake. Right before I'm about to stop I hear this rattling but more like a clunk because it sounds a little deep. It almost sounds like very low exhaust backfires. Any ideas what it could be? I don't think it's the exhaust but maybe it is. I just can't pinpoint it.

    Do you feel a rattle anywhere? Where does the noise come from? And you say you hear it right before you are about to stop, so does that mean, after you have put it in neutral and before you hit the brake? Or while braking right before you come to a complete stop?

    It sounds like it's right under the car. I don't feel anything I can only hear it. The noise seems to start after my foot is on the brake. Although if I just put it in neutral and let it coast I can also hear it. Basically when the rpms are under 2k and the car is coasting (not under load) I get that rattle. I don't think it matters if I'm stopping but I just hear it more often when I'm stopping maybe because everything else is quiet (wind, exhaust, etc.)

    If you have an aftermarket exhaust... my first thought is that bumping your floor pan. But usually you can feel it.

    Yeah I do have loudmouth ii catback. It's strange I can actually hear it better with the windows up. It doesn't feel like any knocking or anything else really. I can just hear it.

    Maybe your brake pads are rattling? Maybe a shim worked its way loose. I know I have seen cars at my shop with loose brake pad shims.
