#1: Backbox rattle Author: brimbo, Location: South ShieldsPosted: Fri Aug 26, 2011 3:43 am ---- Noticed my backbox is making a rough rattling noise, I got told it sounds like the baffles inside my backbox, and its defiantly not my heat shield.
Far as I knew backbox's were hollow and the sound was judged on the dimensions
Is it worth fixing or should I just replace it all together ?

And loose exhaust clamps are also common suspects. Just take it off and see if it is the problem. If it is then isn't worth fixing no.

Sounds about right,the baffles inside are made of mild steel and they rust which makes them come loose and then they rattle about
If you give the backbox a thump you can normally hear the baffles rattling
If they are loose then there's nothing you can do except replace it

It should be joined to the centre section by a clamp
