Emission Purpose Metallic catalytic substrates are designed to reduce harmful emissions by transforming toxic gases into safer compounds like carbon dioxide and water vapor. They ensure optimal performance for petrol-powered vehicles, meeting strict emission standards. Fits directly into original catalytic converters! Materials Used Our substrates are built using advanced materials for exceptional durability and performance: High-Grade Metal Alloys: Provide heat resistance and structural stability. Precious Metals: Coated with platinum, palladium, and rhodium for effective catalytic reactions. Ceramic Washcoat: Enhances the surface area for maximum efficiency. Key Benefits Direct Fit: Can be placed in the original catalytic converter housing without needing an EC license, ensuring it passes technical inspections effortlessly. Cost-Effective Solution: Ideal for catalytic converters after the manifold in tight spaces, where universal converters cannot fit. Changing only the substrate offers a much cheaper alternative to replacing the entire unit. High Performance: Equivalent to or better quality than the original catalytic converter for a fraction of the cost. Compliance: Fully compatible with EURO 4, 5, and 6 standards. Design and Structure Our metallic substrates feature a honeycomb design for maximum efficiency: 400 CPSI: Standard configuration offering balanced flow and performance. 300 CPSI High Flow: Ideal for performance models, reducing backpressure while enhancing exhaust flow.
