HJS FIA-Approved Motorsport Catalysts
The latest generation of catalysts are characterised by 30% less weight in relation to catalysts built using existing materials and techniques. Back-pressure has been reduced by a further 15%, and the exhaust gas pollution reduction is optimised. The thickness of the foil (0.11mm) remains unchanged but is now of a PE Foil design which uses perforations to reduce weight and increase flow. Although the products may be new, they have been extensively tested and shown to offer the same high-levels of durability and reliability of existing products. All HJS Catalysts are available through ourselves.
