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)
