New Coilovers Banging noise??

[HOLLA]

Hi guys had some coilovers fitted yesterday and im getting a banging noise from the rear whenever i change direction or the cars weight goes from side to side?

If i also push down in my boot i also the get same noise?

any ideas???

Topmounts at the rear dont sound like they are tight enough?

Or cud it be exhaust hitting the boot/ heat sheild?

Chances are it's the exhaust.
