Cast Downpipes are designed to enhance gas-flow and heat management, increasing efficiency and performance. 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. This results in a freer-flowing catalyst, improving gas-flow and overall performance. - Enhances gas-flow and heat management - High-Flow Sports Catalyst reduces cell density to 200 cells - Maintains emission regulations for daily driving - Improves overall exhaust performance Specifications: - Pipe Diameter: 70.00 - Installation Time: 2.5 to 3.5 hours (including removing OE system) - Race Product: Yes - EMarked: No Kit comes with: - F5151: Adapter to Milltek Sport OPF/Cat Back Systems 70 O.D. to 70 I.D. 130 long - MSVW491: Cast Downpipe with 200CPSI Hi Flow Sports Cat - MSVW491 - MSVW492REP: Non-Resonated OPF/GPF Bypass Pipe - MSVW492REP Vehicle Compatibility: - 2019-2021 Volkswagen Polo GTI 2.0 TSI (AW 5 Door PRE Facelift Models only) - GPF/OPF Models Only
