Catalytic Converters

The catalytic converter is a marvel of chemical and engineering technology. It cleans gases passing through vehicles’ exhaust systems. The process is a complex combination of substrates and precious metal catalysts. Our chemists and metallurgical engineers have this expertise.

AP is a proven leader in the development and manufacturing of technologically advanced catalysts and catalyst systems. Our products meet and exceed the demands of the global emissions marketplace. As an innovator in an industry steeped with regulations and exacting requirements, our catalysts are engineered to the most stringent emissions standards set forth by EPA, CARB and engine-makers worldwide.

Creating an effective solution for each customer’s specific requirements is our goal. AP is has a full line of catalytic converters and including hard-to-find direct fit manifold and warm-up catalytic converters, as well as a full line of accessories for easy installation.


Diesel Particulate Filters (DPF) and Diesel Oxidation Catalysts (DOC)

DPFs and DOCs are an important part of your vehicle’s emissions system. DOCs reduce harmful emissions by converting carbon monoxide (CO) and hydrocarbons into carbon dioxide (CO2) and water. DPFs remove any remaining diesel particulate matter or soot that the DOC could not oxidize.

DuraFit leverages extensive field application knowledge and benchmarking to improve designs and materials – providing a line of exceptionally durable emissions parts. All DuraFit DPFs and DOCs are designed, built and tested to stringent standards in the USA and meet all applicable EPA standards.*
