BMW M135i (F40) 2020-2023 Akrapovic SO - Slip-On ECE Type Approval

In the case of vehicles with a maximum mass not exceeding 2000 kg:

Beautifully crafted from high-grade titanium, this lightweight exhaust system is finished with eye-catching carbon-fiber 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 engines 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 Akrapovič dyno against a BMW M135i using a standard stock exhaust
