Protect your BMW’s vulnerable underbody components from costly damage with our new Aluminum Skid Plate Kit, an exclusive design for BMW G2X M340i/M440i xDrive.

From the factory, BMW G2X cars are equipped with a weak plastic undertray. This flexible piece can't withstand the rigors of daily driving, leaving critical parts like the engine oil pan and core support exposed to damage from potholes, speed bumps, and road debris. Upgrade your underbody protection with our durable aluminum skid plate, engineered for superior performance, lasting durability, and improved airflow.

Features & Benefits:

Made from lightweight yet robust 8GA (3.3mm) 5052 aluminum, providing unparalleled underbody protection without adding excessive weight over the front axle. Features a durable one-piece design that ensures strength and resilience against impacts while also replacing the flimsy OEM undertray. High-quality milled aluminum finish for a seamless look that integrates perfectly with your BMW’s underbody components. Optimizes performance by maintaining factory aerodynamics while improving ground clearance and airflow. Includes all necessary mounting hardware for a straightforward installation. Made in the USA! Product Development: In the development stages of this project, our R&D team employed state-of-the-art tools, including FARO laser scanning, SolidWorks 3D CAD modeling, and extensive long-term testing, to create a skid plate that delivers exceptional protection and reliability. This skid plate isn't just an upgrade—it’s a statement of quality and innovation.

Installation: To ensure seamless installation, we've provided an easy-to-follow, step-by-step installation guide.

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)
