Clink noise coming for rear.

[Jot17]

Hey guys,

I started my car today and just took it down the road and as I have bumps and small pot holes down my road, when I went over a small pot hole there was a metal kind off noise coming from the rear I think it was the driver side but not sure, my exhaust has abit off movement as one off the brackets are broken but I know what that noise sounds like this was a noise like two thin metal plates hitting each other and making a clink clink noise, it starts off going clink clink then it disappears slowly going quieter and quieter, I was only doing 4000rpm in first so wasn\'t going fast, anyone know what it might be? I couldnt spot anything under the car so don\'t know, and I went down a brand new layer surface and there was know noise. :3Confused:3Confused

Thank You.
