Once more enhancing the S55's sound, the second-generation AWE Exhaust Suite for the BMW F8X M3 and M4 features a unified design for both OPF euro and non-euro spec cars (confirmed fitments from 2015 to 2020).
Its catback design is 50-state legal, ensuring a fantastic sound while keeping all catalysts intact.
An X-pipe that is precision-engineered unlocks a clean S55 tone, and it's available in both valved SwitchPath and rowdy Track Edition variants.
The SwitchPath maintains factory valving and retains M-Sport button functionality.
With a 3' CNC mandrel-bent catback configuration, it delivers up to 12 hp and 16 ft-lbs of torque at the wheels.
The Track Edition includes AWE machined mechanical valve simulators, and tip options include 102mm double-walled, slash-cut tips in chrome silver or diamond black.
Handcrafted from U.S.-sourced .065" wall T304L stainless steel, it is proudly engineered, designed, and manufactured in-house at AWE, with a no Check Engine Light guarantee and perfect fitment.
It features the AWE Lifetime Exhaust Warranty.
