Turn up the drama on your BMW M8 with Milltek’s OPF-GPF bypass sections. Designed for OPF-equipped cars from 2020 onwards, these straight-through replacement pipes connect to the factory front pipes and are intended to be used with a Milltek particulate filter-back rear system. Expect a cleaner, louder V8 soundtrack, faster exhaust gas flow and a more engaging drive without intrusive cabin boom.
