When I shut off car the exhaust pipes makes a clicking sound, I know the pipes are probabably just cooling down but this does it constantly plus i also hear it when idling. Is this normal, Could this be converter problem?

Convertor will usually set a code if there is a problem with convertor.

You will probably have to get car off ground and inspect exhaust system for loose bolts, heat shields, missing hangers.
