Motorsport Catalysts

HJS offers a universal non-regulated catalytic converter system with 100 cpsi for motor sport applications. For the different cubic capacity classes of racing vehicles, a corresponding catalytic converter with a specifically adapted catalytic converter volume has been developed.
The new generation of HJS high performance catalysts with FIA homologation are characterized by 30 % less weight in relation to the so far used parts. We have reduced the backpressure about another 15%, the exhaust gas pollution reduction is optimised as well. The thickness of the foil (0.11 mm) persists unchanged. For the catalysts with the new developed foil we can guarantee the same durability in relation to our so far offered products.

For all Cup series and standard motorsport cars with exhaust temperature not over 950 degrees centigrade, HJS offers a special 100 cpsi catalyst which combines the high quality of HJS products with a best price calculation.
The target group are production-based F / Gr. N / R (non-turbocharged) cars. The catayst R 9012-10 Cup is the right choice for all cars up to 1600 ccm/ 180 hp, the catalyst WRC 1112-10 CUP for all cars up to 2000 ccm/ 240 hp and the catalyst WRC 1279-10 Cup for all cars up to 2000 ccm / 300 hp.
The Cup catalysts are based on the well known HJS product line of motorsport catalysts, that guarantees best quality and durability for years.

Ultra-light catalytic converter reduces weight by up to 30%: With the new ultra-light metal support it was possible to reduce the HJS FIA homologated catalyst’s overall weight by up to 30%. The thickness of the catalyst casing can be reduced from 1.5 to 0.5 mm by use of the new three-dimensional bionic structure. In connection with the previously used perforated foil (PE) there is a significant weight reduction of over 50% compared to products of competitors.
The smaller difference in thermal capacity of the steel foil matrix and the casing is another advantage of the product. As a result the durability doubles under the extremely high thermal shock loads commonly experienced in motorsport.
