The range of cast downpipes is designed to enhance gas-flow and heat management, increasing efficiency and performance gains. The HJS High-Flow Sports Catalyst offers high quality and strong performance as an aftermarket catalyst. This product reduces the density of OEM catalysts while maintaining emission regulations for daily use. Standard OEM catalysts typically have 500-600 cells, while the high flow catalyst reduces this to 200 cells, making it freer-flowing and improving gas-flow and performance. All performance exhaust systems are manufactured in the UK and distributed to over 90 countries. - Cast downpipes designed for improved gas-flow and heat management - HJS High-Flow Sports Catalyst reduces cell density to 200 cells - Maintains emission regulations for daily usage - Manufactured in the UK and distributed worldwide Specifications: - Pipe Diameter: 76.20 - Installation Time: 1.5 to 2 hours (including removing OE system) - Race Product: Yes - EMarked: No Vehicle Compatibility: - 2017-2022 Honda / Acura Civic Type R FK8 2.0 i-VTEC (Both OPF/GPF & Non OPF/GPF Models) - 2022 and later Honda / Acura Civic Type R FL5 2.0 i-VTEC (Both OPF/GPF & Non OPF/GPF Models) - 2023 and later Honda / Acura Integra Type S (DE5) 2.0 Turbo 320hp
