I’m told cat by original garage , no mention of flexi pipe , Ford have said they want to do there own diagnosis as there’s no eml light on at present ( £160 ) , then £1340 ish if there diagnosis says cat .
Just to add the aftermarket ones are rubbish, they do not line up. They don’t normally fail, this was replaced because it failed the emissions and eml was on. Is there is a reason why it needs replacing
