AWE Resonated Touring Edition Exhaust for 2020-2026 BMW M340i / M440i - Quad Diamond Black 102mm Tips

Fits select 2020-2025 BMW M340i and M340i xDrive, and 2021-2026 BMW M440i and M440i xDrive (G20/G22/G23/G26 chassis).

The AWE Touring Edition Exhaust provides the ideal balance of performance and daily-driver refinement for the B58-powered BMW M340i and M440i. This dual 3-inch downpipe-back system is handcrafted from U.S.-sourced T304L stainless steel with a 0.065-inch wall thickness. This specific resonated configuration is recommended for vehicles equipped with aftermarket downpipes to maintain a sophisticated tone without excessive volume. It features AWE’s patented 180 Technology®, a drone-canceling solution that targets and eliminates specific frequencies to ensure a clear cabin experience at highway speeds.

Engineering highlights include a stamped stainless steel merge that provides a 65% increase in flow over the factory exhaust, facilitating gains of up to 16 hp and 12 lb-ft of torque at the wheels. The system terminates in statement-making quad 102mm double-walled, slash-cut diamond black tips. This is a direct bolt-on upgrade that requires no cutting for installation and includes a No Check Engine Light (CEL) guarantee.
