HJS Tuning Catalyst 90 95 0069 up to 500PS, up to 3000ccm Racing catalyst homologated Diameter: 153mm Length: 349mm Weight: 2,5 kg Connections: from 88,9mm Power: up to 500PS Displacement: up to 3000ccm Homologation: FIA DMSB F3 1012-10 PE Formel 3 The HJS catalyst technology: HJS offers a universal, unregulated catalyst system with 100 cpsi for motorsports. Here the different capacity classes of motor sport vehicles, a corresponding catalyst is associated with a specially matched volume. New generation of HJS motorsport catalysts with FIA / DMSB Homologation: HJS motorsport catalysts of the latest generation have 30% weight saving of in relation to the catalysts previously used. The film thickness (0.11 mm) remains unchanged. By film/s perforations much weight is saved, at the same time reduces the exhaust back pressure by up to 15%. The exhaust gas reducing effect is further enhanced by the optimized gas management. The newly developed lighter foil (PE) ensures the same shelf life as the products used so far.
