The Milltek Sport Particulate Filter-Back range is engineered to compensate for the sound-reducing qualities of the particulate filter and significantly enhance the exhaust system's sound aesthetic. All Milltek Sport performance exhaust systems are designed for a wide range of vehicles. The research and development team works year-round to deliver solutions for performance exhaust requirements.
