Akrapovič BMW M140I (F20/F21) Evolution Line Stainless Steel Exhaust System

Evolution exhaust systems for the BMW M140i are the result of the perfect integration of expertise, the best technology, and the use of the finest materials, available for both the F20 hatchback and F21 3-door body styles. Made from austenitic stainless steel, this system features a newly developed layout with two central link pipes replacing the single factory pipe, a new muffler design, and hand-crafted carbon fibre tailpipes, offering the taste of a more powerful version of an already sporty hot hatch.

The dual-mode, ECU-controlled valve retained from the original design offers stock-level, refined sound during normal cruising, opening into a genuinely joyful, deep sporty note when the car is driven more dynamically. Through extensive testing and development, Akrapovič's sound engineers have coaxed a deep, sporty, higher-frequency sound from the M140i's engine, more akin to a muscle car than a typical turbocharged hot hatch note, while keeping it smooth and eliminating any drone that might hamper everyday enjoyment on a long commute or motorway drive. This system replaces the stock exhaust from the catalytic converters rearward, and comes with EC type approval as standard.

Rather than treating the dual link pipe layout as an afterthought, Akrapovič engineered this new central section specifically to work in harmony with the redesigned muffler, so the whole system behaves as one properly integrated unit rather than a collection of parts bolted together. The result is genuinely improved exhaust flow throughout, translating into a measurable power increase alongside the sound and weight benefits, without sacrificing the refined character this platform is known for when you're not pushing it hard.

Optional upgrade available: compatible with the Akrapovič Sound Kit, giving you full independent control over the exhaust valves and letting you switch between sound modes on demand, separate from the car's drive mode entirely.
