From 2017, many vehicles have been equipped with a particulate filter to further reduce emissions. The Milltek Sport Particulate Filter-Back range is designed to compensate for the sound-reducing qualities of the particulate filter and significantly improve the sound aesthetic of the exhaust system. All performance exhaust systems are designed for a wide range of vehicles. The research and development team works throughout the year to deliver solutions for performance exhaust requirements.
