CARGRAPHIC / HJS Catalytic Converters

3-way catalytic converters serve to improve the pollutants emitted by the combustion engine. They convert carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx) into carbon dioxide (CO2), nitrogen (N2) and water (H2O).


High-quality T38 coating with 4 times the amount of precious metals

In contrast to conventional sports catalytic converters, CARGRAPHIC catalytic converters are coated with much higher quality T38 coating - Almost 4 times the amount of precious metals, consisting of PlatinumPalladium and Rhodium.



CARGRAPHIC catalytic convert have a honeycumb body constructed in HD-Matrix design which stands for High-Durability.


Radial Groove

The radial groove in the jacket prevents any movement of the honeycomb body under high exhaust pressure and thus supports its longevity.


More Power - Constant OBD values

Thanks to this feature, CARGRAPHIC catalytic converters are particularly suitable for high-performance vehicles or sports cars whose performance is to be significantly increased without manipulating the original OBD2 values in the engine control unit.



Only HJS catalysts marked "for CARGRAPHIC TS" have the special HD matrix structure and the high-quality T38 coating.
