AWE SwitchPath Axle-Back for the 2018–2019 BMW M5 (F90) 4.4T AWD retains the factory mid-section and factory valve behavior while reducing rear weight and maintaining a 3" diameter flow. The system is modular—Performance Mid Pipes are available to form a full cat-back—and uses 4" double-walled AWE tips. Note: fitting Performance Mid Pipes or an Axle Back alone may require cutting; combined mid pipes plus axle back do not.
