Akrapovič BMW M135i (F40)/X2 M35i (F39)/Mini JCW Clubman ALL4 (F54) Slip-On Line Titanium Exhaust System
Beautifully crafted from high-grade titanium, this lightweight exhaust system is finished with eye-catching carbon-fibre tailpipes, providing a full sensory delight. The exhaust valve—with its housing cast in Akrapovič’s in-house foundry—delivers a rich sound with an emphasis on high frequencies, particularly noticeable when shifting through the gears. This is combined with a deep tone that enhances the car’s engine sound without causing any discomfort or drone for the occupants. A specially engineered Y-split reduces flow noise while maintaining optimal pressure pulse distribution, resulting in a strong sound and ideal flow path.
Constructed with lightweight materials and a unique configuration, the exhaust system reduces overall weight by 9.4 kg, which is a 55.6% savings compared to the stock version. The design and build of the exhaust system optimise power and torque levels across the entire rev range, achieving performance gains of 3.3 kW (4.5 hp) at 5,350 rpm and an increase in torque of 5.9 Nm at 5,300 rpm. These improvements were recorded during in-house tests with back-to-back runs on the Akrapovič dyno against a BMW M135i with a standard stock exhaust. For an even further upgrade, the Slip-On Line (Titanium) exhaust system can be complemented with the optional Evolution Link pipe set (SS).
