Product Description

The AWE 3025-43301 SwitchPath Axleback Exhaust is engineered for 2020-2025 BMW X3 M (F97) and X4 M (F98) equipped with the S58 3.0L turbo engine. Constructed from T304 stainless steel with mandrel-bent tubing and finished with quad 4.5" slash-cut tips, this axle-back delivers an aggressive exhaust note, improved flow, and a refined upgrade over stock mufflers -- while preserving factory valve operation and emissions compliance.

Thanks to AWE's SwitchPath valved muffler and 180-Technology® drone-canceling design, the 3025-43301 gives you the best of both worlds: a smooth, subdued tone for daily driving, and a loud, sporty exhaust note under throttle. Installation is bolt-on using stock hangers and hardware. When paired with compatible mid-pipes, this exhaust can unlock modest horsepower and torque gains while maintaining a legal, emissions-friendly setup. Ideal for enthusiasts who want performance, sound, and clean installation without sacrificing comfort or compliance.
