Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Milltek GPF OPF Bypass for BMW M8 and M8 Competition F91 F92 4.4 V8 Twin Turbo 2020 onwards — the ultimate BMW M8 exhaust upgrade for OPF GPF cars only. This Milltek OPF delete bypass pipe set fits to OE downpipes and is designed to work with the Milltek Sport Particulate Filter Back System only, delivering maximum sound, flow and motorsport character while retaining premium refinement.

Made in the UK from aerospace grade type 304 non-magnetic stainless steel, every Milltek Sport GPF OPF bypass is hand finished by experienced craftsmen for exceptional durability and a perfect fit.
