HJS Motorsport Catalysts

HJS Motorsport Catalysers have developed a range of universal racing catalysers with a 100-cell internal structure. A catalyser with a specifically optimised volume has been designed for each engine capacity. The new generation of FIA-approved HJS Motorsport catalytic converters stands out for its significant weight reduction, weighing 30% less than the products used to date. Back-pressure has been reduced by a further 15%.
