HJS Emission Technology is Europe's leading manufacturer of motorsport catalysts. Since 1990, HJS has developed and produced catalysts and exhaust systems for motorsport. HJS?s Motorsport department cooperates closely with the German Motorsport Federation (DMSB), the FIA (Federation Internationale de l?Automobile) and vehicle manufacturers.
HJS ECE Catalysts - HJS?s ECE R103-approved tuning catalysts have been developed on the basis of our motorsport catalysts. Our 200 cpsi catalysts are the right component for self-designed exhaust systems. You will achieve higher horsepower with less backpressure without having problems with your EOBD or MOT inspection. The specially designed HJS cones provide an ideal exhaust gas flow into the catalyst, which contributes to optimal power performance. Please take a look at the vehicle range documents to see which vehicles have been approved according to the ECE 103R regulation. The catalyst (i.e. type and ECE approval number) is identified on the tag attached to the cone. According to the ECE approval, the installation positon of the HJS catalyst is the same as for the standard-production component. If the original catalyst is equipped with heat shields, the tuning catalysts must also have appropriate heat shields.
