"cleaned" cat con lol. That is the reason it got destroyed.
You don't clean a cat converter that often. And if you put acid in it to clean it that 100% means it is getting destroyed. Not cleaned!!!
All over the world it is accepted that cat converters can't really be cleaned. It gives false sense to people when they think they have cleaned it. But not really. It is usually replaced. But not in Pak. Still OK, try safe cleaning products but not every 30k.
And give us a favor do put a cat converter in your car.
You are contributing to polluting our environment when you take out the catalytic converter.
Major air pollution.
Cars without proper functional catalytic converters need to be banned from roads.
