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