Frequently Asked Questions Ask APW
Can a high flow catalytic converter improve a Toyota Pickup's overall engine performance?
Answer: Since a catalytic converter acts as a choke point in a Toyota Pickup's exhaust system, installing a high flow catalytic converter may help increase an engine's performance. The engine can gain about five horsepower after installing a high flow catalytic converter. Overall torque is also increased across the engine's lower RPM ranges. This also improves the rest of the pickup's power output. Also, modern high flow catalytic converters can clean better than a stock Toyota Pickup catalytic converter.
Is it legal to install dual catalysts or dual exhausts on a Toyota Pickup?
Answer: Unless a Toyota Pickup was initially designed with a dual exhaust system or a dual catalyst configuration, installing dual catalytic converters is not advised. The EPA advises that a proper converter must be installed on a customer's car or truck. If the wrong converter is installed on a Toyota Pickup, its performance will be affected and it can cause severe engine damage.
What are the advantages of installing a three-way plus air catalytic converter on a Toyota Pickup?
Answer: Basically, there are three types of converters available for a Toyota Pickup; two-way, three-way, and the three-way plus air. These different types of converters have different methods to reduce harmful exhaust gases. A two-way catalytic converter first oxidizes carbon monoxide into carbon dioxide. It simultaneously oxidizes the partially burnt fuel into carbon dioxide and water. Two-way converters are designed for diesel engines. Three-way catalytic converters, on the other hand, function like a two-way converter, and they can reduce nitrogen oxides into harmless nitrogen and oxygen. The advantage of a three-way plus air catalytic converter is the extra air pumped into its center. With the additional air pumped between the two separate ceramic-substrate coated catalysts, it significantly improves the catalytic converter's oxidation capabilities.
