Milltek Sport exhaust system for BMW 1 Series F20-F21

Frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no intermediate muffler): it is the most expressive, with more crackle on lift-off. On the other hand, a slight drone may appear at certain engine speeds on long journeys. If you do a lot of highway driving, compare it with the resonated version.
• What about the neighbors in the morning? The valves are controlled as on the original system: closed and discreet at startup or in comfort mode, fully open in sport mode.
• Installation: the system uses the original mounting points. A repair shop with the right equipment usually fits it in one to two hours.

Why choose Milltek Sport?

A benchmark among European tuners, Milltek Sport develops each of its systems directly on the vehicle. Mandrel bends, careful welds and aerospace-grade stainless steel ensure a system that lasts and sounds right.
