      AP Exhaust Technologies® Overview

    • OBDII ENGINEERED Catalytic Converter

      AP Exhaust Technologies® OBDII by Design

      THREE-WAY No/Air OBDII By Design US-EPA Compliant catalytic converters are efficient at the oxidation of HC’s and CO and very efficient at the reduction of NOx, storing O2, and the steady release of O2 into the exhaust stream. OBDII Designed product is engineered to deal with the specific demands of today’s OBDII engine operating systems and emission gas levels.


      Engineered Benefits:


      • Larger total substrate size
      • Increased precious metals loading
      • Improved O2 storage and release
      • Lower emissions output
      • Long-term reliability

    • AP Exhaust Technologies® Substrate Cut

      The catalytic converter is a marvel of chemical and engineering technology. It cleans gases passing through vehicles’ exhaust systems. Catalytic converters typically consist of a ceramic or metal honeycombed monolith substrate that carries precious metal catalysts. The coated substrate is wrapped in a protective thermal mat that expands when heated, securing and insulating the substrate, which is contained in a tough stainless steel shell and becomes a component in an engine exhaust system. As exhaust gases pass over the catalysts, chemical reactions occur and convert pollutants into harmless gases and water. Hydrocarbons combine with oxygen to become carbon dioxide. Nitrous oxides react with carbon monoxide to produce nitrogen and carbon dioxide, and with hydrogen to produce nitrogen and water vapor. The companys chemists and metallurgical engineers have this expertise.

      AP is a proven leader in the development and manufacturing of technologically advanced catalysts and catalyst systems. The companys products meet and exceed the demands of the global emissions marketplace. As an innovator in an industry steeped with regulations and exacting requirements, AP catalysts are engineered to the most stringent emissions standards set forth by engine-makers worldwide. Whatever the market – automotive or industrial, recreational or power equipment, AP is committed to satisfying the needs of each individual customer.


      Creating an effective solution for each customer’s specific requirements is the companys goal. The finest technological advancements are used in the development and manufacturing of catalytic systems that meet or exceed global requirements for the control of combustion emissions from any fuel and all industries.
