Milltek Cat-back GPF-back Resonated Exhaust with Polished GT-90 Trims for BMW M140i F20 F21 LCI OPF 2019-on
Upgrade your BMW M140i exhaust with the Milltek Sport cat-back GPF-back resonated system, complete with polished GT-90 tailpipes. Designed specifically for the F20 and F21 LCI OPF models from 2019-on, this premium performance exhaust delivers that sought-after M140i sound with everyday refinement, precision fitment and standout road presence.
Every Milltek system is designed, developed and hand finished in the UK using aerospace grade type 304 stainless steel. This non-magnetic T304 material resists discolouration, offers exceptional durability and is used throughout the pipework, silencers and hardware. Mandrel-bent tubing maintains a constant radius for optimised gas flow, while carefully selected bore diameters enhance performance without sacrificing mid-range torque. Extensive acoustic tuning ensures a sporty, crisp exhaust note with no unwanted NVH, drone or cabin resonance.
