Beautifully crafted from high-grade titanium, this lightweight exhaust system is finished with eye-catching carbon-fibre tailpipes and is a full-on sensory delight. The exhaust valve – with its housing cast in the in-house foundry – gives the exhaust a rich sound with an emphasis on high frequencies, especially when shifting through the gears, all allied to a deep tone that enhances the car's engine without any discomfort or drone for the occupants. A specially engineered Y-split reduces the flow noise without any compromise to the pressure pulse distribution, thus offering a strong sound and optimal flow path. The use of lightweight materials and a different configuration reduces the overall weight of the exhaust by 9.4 kg, a saving of 55.6% on the stock version. The design and construction of the exhaust optimize the power and torque levels throughout the rev range, with performance increased by 3.3 kW (4.5 hp) at 5,350 rpm and torque up by 5.9 Nm at 5,300 rpm. This was achieved during in-house tests with back-to-back runs on The Akrapovic dyno against a BMW M135i using a standard stock exhaust. For a further upgrade of the Slip-On Line (Titanium) exhaust system, an optional Evolution Link pipe set (SS) is available.The ECE type-approval certificate is valid only for 2020 model year cars equipped with an Otto/gasoline particulate filter.The exhaust system can be fitted on the BMW M135i XDrive model.To install the Slip-On Line (Titanium) exhaust system, the stock exhaust system must be cut
