Milltek Valved OPF / GPF-Back Exhaust System for 4M Audi SQ7
Toward the end of 2018, many vehicles began to adopt gasoline/otto particulate filters in an effort to lower emissions. In response, Milltek Sport introduced its Particulate Filter-Back series, designed to lessen the sound muffling effects of these particulate filters. This innovation greatly improves the exhaust system’s sound quality, offering a more satisfying listening experience.
