Giving much improved sensory experience, this lightweight exhaust is beautifully crafted from high-grade titanium and finished with an eye-catching carbon fibre tailpipes. With exhaust valve – with its housing being casted in the in-house foundry - the sound from the exhaust is of a richer and higher frequency than stock, especially when shifting through the gears, all allied to a deep sound that enhances the car’s engine tones and gives no discomfort or drone to the occupants. A specially engineered Y-split enables the reduction of streaming caused by the OPF without any compromise to the pressure pulse distribution, thus offering a stronger sound and optimal flow path. Lighter than stock due to the use of titanium and a different configuration, the design and construction of the exhaust leads to an optimisation in the power and torque levels throughout the whole rev range with performance increase of 3,3 kW at 5350 RPM and torque increase of 5,9 Nm at 5300 RPM. Optimized flow path of exhaust gases opens tuning capabilities, something that can be elevated to higher level with the addition of the optional Evolution Link pipe set (SS) to give a further performance upgrade. The system is ECE type approved for cars equipped with Otto/gasoline particulate filter. The system can be fitted on BMW M135i XDrive 2020 model. For installing the slip-on system, the stock exhaust system has to be cut. Please read the instructions carefully before the start of the installation.
