strange grating metallic noise fron zorst on 172 ph2

[cliobritt]

It only seems to happen when i rev the engine when still...and only when i lift off the gas. it coughs slightly from the end of the zorst at a standstill too could that be anything to do with it?
Oh and i cant find any blows..

dog bone mount on engine? or u sure it's the exhaust?

that sound like the same 4k rattle as on mine. its the center section of the exhaust. mechanic told me that its caused by the baffles inside the silencer rusting and snapping. i've just ordered a full ashley competition exhaust for my 2003 172 - 145 big ones inc delivery..!
