The Milltek Sport Turbo-Back range provides performance enhancements for turbocharged vehicle owners seeking to tune their vehicles. The exhaust system features an enlarged diameter throughout, improving gas-flow properties and reducing back pressure due to decreased restrictions, while delivering an 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.
