ya know i always wondered why my car fealt so much better after i washed it
just felt like the car was happy to be clean

In regards to HOW a cat works and the differences between the types....
Two-Way Oxidation Converter
A Two-Way converter, used on cars between 1975 - 1980, oxidizes unburned harmful hydrocarbons and carbon monoxide into water and carbon dioxide. The first vehicles with catalytic converters had Two-Way Oxidation only capabilities.
HC, CO OXYDIZES TO H20 and CO2
Three-Way Reduction/Oxidation Converter
A Three-Way converter is a triple purpose converter. It reduces nitrous oxides into nitrogen and oxygen. And, like the two-way converter, it oxidizes unburned harmful hydrocarbons and carbon monoxide into water and carbon dioxide.
NO2 REDUCES TO N2 and 02
HC, CO OXIDIZES TO H20 and CO2
Three-Way + Air Reduction/Oxidation Converter
A Three-Way + Air converter performs the same functions as the Three-Way converter. It oxidizes and reduces. The difference is the addition of secondary air between the two internal catalyst substrates that improves the oxidation capabilities of the converter. The secondary air is pumped into the middle of the converter between two seperate catalyst coated ceramic substrates. The front ceramic performs the reduction and the back ceramic performs the oxydation. Its like having two converters in one.
NO2 REDUCES TO N2 and 02
HC, CO OXIDIZES TO H20 and CO2
Pre-Converter and Main Converter
Each of the three types of converters mentioned above have a common need in order to function properly. Each needs to reach a minimum operating temperature before any emission reduction or oxidation takes place. This warm-up period immediately after a vehicle is started is when the catalytic converter is least efficient and the vehicle expels the most pollutants. Some vehicles employ a pre-converter in the exhaust system immediately after the manifold to help during this warm-up period. The pre-converter’s small size and proximity to the engine allow it to heat up and start functioning in less time than the main converter. It also pre-heats the exhaust gasses and helps the main converter reach operating temperature sooner.

From all of this that is said which one would be the best for High Flow performance when running a Turbo like me

He said popo!! Nobody within the Chicagoland area knows what that means cept me! Bwahaha..just another reason why Red rocks.
