Choosing a Milltek filter-back for the Mini F66
The Cooper S filter-back and the JCW filter-back are separate listings, so match yours to the badge on your car. Both fit behind the factory particulate filter and come resonated, listed as EC approved and the quieter choice with less drone, or non-resonated for more volume. Tip choices include an OEM-style downturned outlet and GT-100 or GT-115 tips in polished, Cerakote Black, brushed or burnt titanium, plus JET carbon fibre; see the tip styles page.
The GPF/OPF bypass for each model is a louder, motorsport-oriented part. It comes in versions to suit the OE or a Milltek system, so pick the one that matches your exhaust.
