Product Details

AWE has one vision: To unlock performance. AWE has a unique facility where every step, from design to production, is completed within their facilities. This results in state-of-the-art exhausts with unparalleled quality control and top tier performance.

The SwitchPath Exhaust for your F90 M5 is a versatile system that responds to the exhaust valve commands sent from your BMW ECU. This allows you to manipulate the level of sound output using the different BMW driving modes. Select the comfort mode for those early mornings in the neighborhood, and sport mode when you're ready to unleash all of the power and sound. This exhaust delivers a fine-tuned sound from your S63 motor, that is sure to turn heads. Choose from Chrome Silver and Diamond Black tip finishes.
