Will the catalytic converter be damage due to excessive heat. - Visitor
They can handle a lot of heat but yes they can get too hot. You can have it tested. Ignition problems can often cause cat failure or just age but make sure to resolve any issues before replacing them or the new ones could fail as well. Fuel problems like running lean can poison them too. - jason94
