AWE Exhaust Suite for BMW F3X 340i / 440i

Unlock the true sound and performance potential of your BMW F3X 340i or 440i with the AWE Exhaust Suite, engineered specifically for the B58-powered platform. Designed to deliver the perfect balance of aggressive tone, refined sound quality, and measurable performance gains, this system is a no-compromise upgrade for enthusiasts who want more from their BMW.

At the heart of the system is AWE’s proprietary 180 Technology®, a patented drone-canceling solution that eliminates unwanted exhaust frequencies while allowing the engine’s natural tone to shine. The result is a deep, powerful exhaust note outside the car with a comfortable, drone-free driving experience inside the cabin.

The axle-back exhaust features a straight-through performance design paired with a full 3-inch CNC mandrel-bent system that improves exhaust flow and unlocks gains of up to 9 horsepower and 11 lb-ft of torque at the crank. This design provides a noticeable improvement in throttle response and overall engine character without sacrificing daily drivability.

For drivers looking to push performance further, AWE also offers a Performance Mid Pipe option. This non-resonated mid pipe replaces the factory resonator with straight-through 3-inch T304 stainless steel tubing to deliver an even more aggressive tone and increased exhaust flow. (Note: Performance Mid Pipe is intended for racing applications.)

Constructed from U.S.-sourced T304L stainless steel and handcrafted at AWE’s Pennsylvania facility, the system is built for durability, precision fitment, and long-term performance. Multiple tip options allow owners to customize the final appearance with 90mm or 102mm double-walled tips available in chrome silver or diamond black, each featuring the signature AWE logo and adjustable depth for a perfect fit.

Backed by AWE’s Fitment Guarantee, No Check Engine Light Guarantee, and Lifetime Warranty, the Exhaust Suite for the F3X 340i / 440i delivers performance, sound, and reliability that BMW enthusiasts expect.
