Here are a few reasons, facts, and stats about catalytic converters:

"Catalytic converters decrease hydrocarbon emissions by about 87 percent, carbon monoxide by 85 percent and nitrous oxide by 62 percent during the expected life of a vehicle."

"In 1985, the Environmental Protection Agency estimated that catalytic converters saved at least 10 times more in health costs than the price of a catalytic converter."

"Engineers estimate that during the last 11 years 130 million catalytic converters used in the U.S. have eliminated automotive pollutants that-if unchecked and unabated-could have covered the country with a toxic blanket of carbon monoxide more than 500 feet deep."

"The U.S. Environmental Protection Agency (EPA) data shows that due to emission controls, vehicles now sold in the U.S. emit 96 per cent less carbon monoxide, 98 per cent less hydrocarbons, and 90 per cent less oxides of nitrogen than vehicles sold in the early 1970s."

"Currently, 85 per cent of automotive air pollution in the U.S. comes from the oldest 50 per cent of vehicles on the road."

I know that the catalytic converters are good for the environment but what about the effects on the engine?
