A suitable catalytic converter with a specifically adapted catalytic converter volume is available for each of the different engine displacement classes of racing cars. The design (size) of the catalytic converter does not have to take into account a cubic capacity factor (eg for turbocharging).

All HJS Motorsport catalytic converters are DMSB approved. DMSB approval is 100% recognized by the FIA.
