Unlock a louder, more aggressive exhaust note on your BMW M140i (F20/F21 LCI, OPF/GPF) with this Milltek Sport Non-Resonated OPF-Back Exhaust System. Engineered specifically for OPF-equipped LCI models, this non-resonated system maximises exhaust character from the OPF outlet rearwards — delivering a more uninhibited, performance-focused exhaust sound that's a significant step up from the OEM system.
Without the factory resonator to mute the exhaust note, this system produces a more dramatic tone that makes the most of the B58-engined M140i's character. Available in five tip finishes and designed as a straightforward OEM replacement — no cutting, welding, or ECU remapping required. Manufactured from 304L stainless steel in the UK.
Fitment: BMW M140i F20 & F21 LCI (OPF/GPF equipped models)
