HJS Motorsport catalytic converters with 100 cpsi

HJS offers a universal, non-controlled catalytic converter system with 100 cpsi for motorsport applications. A suitable catalytic converter with a specifically adapted catalyst volume is available for each of the different cubic capacity classes of racing vehicles. A cubic capacity factor (e.g. for turbocharging) does not need to be taken into consideration for the design (size) of the catalyst.
