Milltek GPF and OPF Bypass for BMW M240i Coupé G42 xDrive 2022 onwards – SSXBM1225

Unlock the sound and flow your BMW M240i deserves with the Milltek GPF and OPF Bypass, part number SSXBM1225. Designed to fit directly to the OE axle-back system, this high quality Milltek upgrade removes the restrictive Gasoline Particulate Filter section on G42 xDrive OPF and GPF models only. Expect a sharper, more engaging exhaust note and improved gas flow while retaining your factory rear silencer for a clean OE-plus finish.

Every Milltek system is designed, developed and hand-finished in the UK by time-served craftsmen, produced in aerospace grade type 304 non-magnetic stainless steel. This superior material resists discolouration and delivers long-term durability across pipework, silencers and hardware. Mandrel bending ensures constant radius bends for optimised gas flow, with bore sizing engineered to enhance performance while preserving drivability. Milltek’s acoustic development focuses on a sporty, crisp tone that elevates the driving experience.
