From the factory, all BMWs utilize soft rubber or fluid-filled engine mounts. Not only are these mounts prone to degradation, they also allow ample movement of the drivetrain. This translates to looseness in your driveline, commonly associated with missed shifts and a generally isolated feeling.

To improve upon this issue, Black Forest Industries designed these upgraded mounts from the ground up. Their stage one mounts feature a proprietary 85A durometer bushing and bracket/cup design. Maximizing bushing area while minimizing vibration gives this mount the advantage of having the best ride characteristics possible from a urethane mount.

Features:

Perfect fit: Utilizing laser-scanning technology permits seamless integration with the factory engine mount arms. Quality tooling: All bosses are matched replicas with stock locations, and all tool clearances and specs are maintained. Heavy-duty construction: The use of billet aluminum instead of cast creates a mount that is dramatically stronger than its factory cast-construction counterpart. Performance design: 85A durometer bushings are geared toward the spirited driving enthusiast who doesn't mind increasing NVH. Choose BFI Stage 2 for a quality mount that eliminates drivetrain movement.

Note: Stage 2 mounts increase NVH. Therefore, these mounts are not intended to be used on daily driven vehicles.

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

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.
