The BMW 4 Series Performance Exhaust - Rear - AWE Tuning - Axle-Back Track Edition offers an exhilarating upgrade for your 2021-2023 BMW 4 Series. Featuring dual exit, 4.5" diamond black tips, this exhaust system promises to enhance the auditory experience of your vehicle while maintaining compliance with 50-state emissions laws.

The AWE Track Edition begins after the secondary catalyst and provides a full single 3" route from this point, splitting into dual 3" tip outlets. It is designed to increase the volume of the B48 engine, providing an unmistakably aggressive sound without the need for extensive modifications. Crafted from CNC mandrel-bent .065” wall T304L stainless steel sourced in the U.S., this exhaust is a testament to both durability and efficiency. It offers a clean, straight-through design that maximizes performance while saving weight and cost. Engineered for both coupe and sedan configurations, perfect fitment is guaranteed, and the system is backed by a lifetime warranty.

Designed for those who want to amplify their driving experience, the Track Edition is recommended for the 330i when all factory emissions equipment is in place. For the 430i, the louder interior acoustics due to its coupe design make the Touring Edition more appropriate, though the Track Edition offers a spirited tone.
