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 is engineered to provide high quality and optimal performance as an aftermarket catalyst. The 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. This results in a freer-flowing catalyst, improving gas-flow and performance.
