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, enhancing gas-flow properties and reducing back pressure due to lower restrictions. This results in a suitably aggressive exhaust sound.
