Here are a few reasons why removing your catalytic converter will not increase your fuel mileage:
* The catalytic converter does not restrict the flow of air or fuel through the exhaust system. The exhaust system is designed to allow the exhaust gases to flow freely out of the engine, and the catalytic converter does not create any significant restriction. Removing the catalytic converter will not make the exhaust flow any faster or easier, so it will not increase your fuel mileage.
* The catalytic converter helps to burn off unburned fuel. The catalytic converter uses a chemical reaction to convert unburned fuel into water vapor and carbon dioxide. This helps to improve fuel efficiency by ensuring that all of the fuel that is used in the engine is actually burned. Removing the catalytic converter will prevent this reaction from taking place, so more unburned fuel will be released into the atmosphere. This will decrease your fuel mileage.
* The catalytic converter helps to reduce engine emissions. The catalytic converter helps to reduce harmful pollutants from being released into the air. Removing the catalytic converter will increase the amount of pollutants that are released into the air, which can have a negative impact on air quality.
Overall, removing the catalytic converter on your 2001 Ford Focus will not increase your fuel mileage. In fact, it may actually decrease your fuel mileage and cause your vehicle to run less efficiently. Additionally, it is illegal to drive a vehicle with a removed catalytic converter in most states.
