What you get

• High-grade austenitic stainless cat-back with centre section and rear silencer
• Evolution Link Pipe Set converting the restrictive single OE mid-pipe to a freer-flowing twin design
• Valve-controlled sound using the factory actuator for quiet cruising or an aggressive tone on demand
• Hand-crafted carbon fibre tailpipes for a premium motorsport look
• EC type-approved for road use
• Compatible with rear-wheel drive and xDrive all-wheel drive models

Why enthusiasts choose this upgrade

Akrapovič engineering unlocks the M140i’s character. The dual mid-pipe layout reduces backpressure to help the turbo breathe, improving response and mid-range punch while trimming overall weight. Around town it stays refined with the valves closed. Open them and you get a deeper, crisper note with that hallmark Akrapovič clarity and no unwanted drone at motorway speeds. It is the perfect balance for daily driving, spirited B-road blasts and track days.

Build quality and finish

Constructed from austenitic stainless steel for strength, heat resistance and long-term corrosion protection, this system is built to last. The carbon fibre tailpipe finishers add an unmistakable motorsport aesthetic that suits the M140i’s rear end perfectly. It is a performance exhaust that looks as good as it sounds.
