The Milltek Sport Turbo-Back range offers performance enhancements for turbocharged vehicle owners seeking to tune their vehicles. The system features an enlarged diameter throughout, providing enhanced gas-flow properties and lower back pressure due to reduced restrictions. This results in a suitably aggressive exhaust sound. The Milltek Hi-Flow Sports Catalyst reduces restriction compared to OE catalysts, allowing for a free-flowing exhaust system to improve engine performance. All Milltek Sport performance exhaust systems are made in the UK and distributed to more than 90 countries worldwide. - Enlarged diameter exhaust system for improved gas flow - Lower back pressure due to reduced restrictions - Hi-Flow Sports Catalyst for increased performance - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 63.50 - Installation Time: 2 to 2.5 hours (including removing OE system) - Race Product: Yes - EMarked: No Kit comes with: - MSPO251: LH Front Connecting Pipe - MSPO252: RH Front Connecting Pipe - MSPO253: LH Rear Connecting Pipe - MSPO254: RH Rear Connecting Pipe - MSPO255: Rear Silencer Balance Pipe - MSPO256: High Flow Sports Cat - MSPO257: Connecting Pipe - MSVW373: Polished GT (round) 100 Exhaust Tip, Standard - MSVW373 Vehicle Compatibility: - 2016-2020 Porsche Boxster 718 GTS 2.5T - 2016-2020 Porsche Cayman 718 GTS 2.5T
