Akrapovic 2020+ BMW M135i (F40) Evolution Link Pipe Set (SS) (Only Fits Vehicles w/V-Clamps) E-BM/SS/6

The Evolution Link pipe set (SS) was tested and developed together with the Slip-On Line (Titanium) exhaust system to provide an ideal upgrade and greater exhaust tuning potential. The use of this configuration is designed for the racetrack and will offer a sporty sound and higher performance. With the elimination of the OPF, the sound levels and frequency content are emphasized, providing an increased sound, leading to an exhilarating tone with crackling and burbling as an enjoyable aural assault on over-run and when downshifting through gears. The change in performance is a noticeable factor: compared in back-to-back runs on The Akrapovic dyno against a BMW M135i using a standard stock exhaust, there a 5.1 kW (6.9 hp) increase in power at 4,250 rpm and 11.5 Nm of torque is added at 4,250 rpm.When installing the Evolution Link pipe set (SS), which is developed for use on closed tracks only, remapping of the ECU is mandatory to prevent potential "Check Engine Light" warning signals. Fitment notice: This product can only be installed on vehicles with the V-clamp connection between the stock downpipe and link pipe.
