Catalytic converter is always there some idiots remove that from jdms it helps decrease the environmental pollution. I cleaned my ride's cat converter from New tech Auto near Water Pump Shahra e Pakistan, contact person Farrukh, number: 0314 2042309.
It took 2500/ Rs. to clean the catalytic converter and once you done that you may feel a noticeable change in your car's performance and fuel average.
In addition you may also service the throttle body of your car, change the air filter and change the spark plugs to Bosch Iridium once.
