Upgrade your BMW F97 X3 M or F98 X4 M with the AWE Tuning SwitchPath Axle-Back Exhaust, crafted from durable 3-inch U.S.-sourced T304L stainless steel for long-lasting performance. The system features a valved SwitchPath™ muffler that maintains factory valve behavior effortlessly—no harnesses or extensions required—allowing for seamless operation and effortless control at the push of a button. Designed with minimal bends for maximum flow, this exhaust system enhances your vehicle's sound and performance without sacrificing reliability. The bespoke X-pipe in the non-resonated Performance Mid Pipes delivers a refined S58 tone when paired with SwitchPath™, providing a more aggressive and sporty exhaust note while maintaining a smooth sound profile during daily driving. These mid pipes are engineered to work seamlessly with the factory axleback or aftermarket options, giving you flexibility in customizing your exhaust setup. The system is compatible with factory or aftermarket mid pipes that maintain the OEM break point, ensuring easy installation and reliable fitment. It retains full factory valve behavior using OEM valve motors, eliminating the need for additional harnesses or modifications. The valved Axleback is available as a complete system, with modular Performance Mid Pipes sold separately for further tuning and performance gains. Expect maximum gains of up to 9 horsepower and 2 lb-ft of torque at the wheels when combining the Axleback with the Mid Pipes, delivering noticeable performance improvements. The quad 4.5-inch double-walled slash-cut tips are available in chrome silver or diamond black, adding a sleek finishing touch to your vehicle's aesthetic. Incorporating drone-canceling 180 Technology®, the SwitchPath™ Axleback ensures a comfortable cabin experience even during spirited drives. Built with a clean, straight-through design, this exhaust maximizes flow and performance while maintaining OEM emissions compliance for all 50 states. Handcrafted in-house at AWE, this system is backed by a lifetime warranty and the No CEL Guarantee for peace of mind.
