From late 2018, many vehicles have been manufactured with a Gasoline/Otto Particulate Filter to reduce further the emissions from the vehicle. The Milltek Sport Particulate Filter-Back range is designed to compensate for the sound reducing qualities from the particulate filter and significantly improve the sound aesthetic of the exhaust system.
