Why are MG HS owners in Pakistan reporting catalytic converter choking problems?

Many drivers say their car loses power and fuel economy due to a blocked catalytic converter. Is this caused by Pakistan’s low-quality fuel o r a weakness in MG HS exhaust design?

Many MG HS drivers face loss of power and mileage due to choking converters. The main causes are Pakistan’s low-quality petrol high sulfur, impurities, and additives and the sensitive exhaust design of turbocharged engines, which makes the HS more prone to blockages than some rivals.
