Why choose Milltek for your M140i
Every Milltek Sport system is designed, developed and hand finished in the UK by time served craftsmen. Constructed from aerospace grade type 304 non magnetic stainless steel, it resists discolouration, delivers long lasting durability and is used throughout the entire exhaust including pipework, silencers and hardware. Mandrel bent tubing maintains a constant radius for optimised gas flow, and carefully enlarged bore diameters over stock help maximise performance while retaining drivability.
Sound and style
The non resonated race setup is chosen for a louder, more engaging soundtrack that suits the character of the BMW M140i. During development, Milltek focuses on acoustic tuning to produce a crisp, sporty tone that enhances the drive without unwanted harshness. The polished GT-90 90 mm tailpipe trims fill the rear bumper perfectly and deliver a clean, motorsport inspired finish. If you are looking for a BMW M140i loud exhaust, M140i non res exhaust, or M140i race exhaust, this system ticks every box.
