At Active Autowerke, it's not ONLY about making as much power as possible but to maximize the enjoyment of the drive. For 40 years, power has been the end result of improved performance due to our relentless desire to develop a refined, quality product. This philosophy behind our performance parts is best represented by one of the newest additions to our G2X/G3X BMW M340i and M440i collection. The Active Autowerke M340i/M440i rear exhaust was carefully engineered to eliminate the overly quiet sound of the factory M340i and M440i exhaust, while also allowing for optimum flow and resonance by reusing the actuator from the BMW valve. Every effort was made in addressing the not so appeasing sound of the stock OEM exhaust, but in designing an exhaust worthy for the BMW 'M' badge. We believe our rear exhaust offers the best combination of sound and performance versus other systems on the market today. Available for both models, this axle-back exhaust gives your BMW the deep, throaty, growl a car of its caliber should have had from the factory! Features: Made in the USA 304 Stainless Steel Low, Deep Sound with stock Valve Control Each exhaust test-fit on the M340i/M440i Exhaust Fixture Guaranteed to fit all G-series M340i and M440i Includes all necessary installation hardware

This is a high-grade lightweight titanium system, finished with hand-crafted carbon-fiber tailpipes and a high-grade austenitic stainless steel link pipe set. The valves on each side are calculated to tailor the sound, and two acoustic reflectors are fitted on the tailpipes to guide the sound into the car’s cabin. Because the Akrapovič Evolution Line (Titanium) exhaust system has two valves, one more than the stock configuration, a TNG controller is included in the product to activate the additional exhaust valve. To make the sound experience even more unique, there are two tuned resonators – developed especially for this new engine – producing a deep, rich, and sporty sound with no unwanted drone or streaming, perfectly aligned with the straight six-cylinder engine. It weighs 21.7 kg, which is 23% lighter than stock. Power gains of 11.8 hp at 5,600 rpm and torque increases of 17.1 Nm at 4,100 rpm were recorded when tested on the Akrapovič dyno

Awaken the B58: Active Autowerke G20 M340i / G22 M440i Valved Axle-Back Exhaust From the factory, the G-series M340i and M440i are notoriously quiet, leaving the sonorous B58 inline-six feeling a bit muffled. Active Autowerke’s valved rear exhaust is the solution for enthusiasts who want to bridge the gap between "daily driver" and "motorsport-inspired." This axle-back system was engineered to replace the lackluster stock muffler with a high-flow, 304 stainless steel unit that captures a deep, hearty growl worthy of the BMW 'M' badge. By reusing the factory valve actuator, this system keeps your driving modes functional—providing a refined tone for the commute and a rowdy, unrestricted bark when you’re in the mood to let it rip. It’s the perfect "OEM+" upgrade that delivers the aggressive sound your BMW should have arrived with. Engineering & Tone Active Autowerke spent months fine-tuning the resonance of this system to ensure it provides a low-frequency rumble without the high-pitched rasp found in cheaper alternatives. Valved Versatility: Retains full integration with your factory BMW drive modes (Eco, Comfort, Sport). High-Flow Design: Maximizes exhaust gas scavenging for improved throttle response and midrange punch. Aggressive Styling: Available with quad tips to fill out the rear diffuser and provide a menacing track-ready look. Key Features: Hand-Built Quality: Fabricated in the USA from premium T304 Stainless Steel. Precision Fitment: Every unit is test-fitted on a dedicated G-series fixture to guarantee a perfect bolt-on install. Motorsport-Inspired Sound: Replaces the whisper-quiet factory muffler with a deep, throaty signature note. All-Inclusive Kit: Includes all necessary clamps and hardware for a straightforward installation. Specifications: Material: Mandrel-bent 304 Stainless Steel Type: Valved Axle-Back (Requires cutting of factory mid-pipe for installation) Valve Operation: Compatible with OEM BMW actuator Vehicle Fitment: * 2019+ BMW M340i / M340i xDrive (G20) 2021+ BMW M440i / M440i xDrive (G22/G23/G26)
