Features:

• Valved Exhaust Technology: The integrated valved exhaust system allows for dynamic sound control, providing the best of both worlds. At lower RPMs, the system maintains a refined, subtle exhaust note, ideal for daily driving or highway cruising.

This material is designed to withstand high temperatures and the stresses of performance driving, guaranteeing reliability and endurance over time.

• Improved Exhaust Flow & Performance Gains: The design of the exhaust system enhances exhaust gas flow, reducing backpressure and allowing the B58 engine to breathe more freely. This results in increased horsepower and torque, improving acceleration, throttle response, and overall performance, especially at higher RPMs.

• Aggressive Sound Profile: With the valves open, the exhaust system produces a more aggressive, full-bodied exhaust note that perfectly complements the sporty performance of your BMW 340i or 440i. The deeper tone amplifies the engine’s natural sound, making each drive more engaging and exciting.

• Adjustable Sound Levels: The valved system offers the ability to control the sound output based on driving conditions. You can switch between a quieter mode for relaxed driving and a louder, more aggressive tone for performance driving. The sound can be adjusted via driving modes or an optional remote control, giving you complete flexibility to suit your preferences.

• Precision Fitment: Specifically designed for the BMW F30 340i / 440i B58 3.0T, this exhaust system offers a direct, bolt-on fitment, ensuring a hassle-free installation process. There’s no need for additional modifications, making it a convenient upgrade for enthusiasts looking for a seamless integration with their BMW.

• Enhanced Turbo Sound: The system helps emphasize the turbo sounds and engine growl, creating an exhilarating auditory experience as the turbocharger spools. This adds a layer of excitement to every drive, making the B58 engine’s performance more thrilling.

• Visual Appeal: Featuring polished exhaust tips, the system adds a sophisticated, sporty look to the rear of your BMW F30 340i / 440i. The sleek design complements the vehicle’s aggressive styling and highlights the performance-oriented nature of the car.

• Long-Lasting Performance: The stainless steel construction ensures the system is not only durable but also resistant to rust and degradation, even under the harshest driving conditions. This makes it a reliable and low-maintenance upgrade for your BMW.

• Potential Fuel Efficiency Benefits: The enhanced exhaust flow may contribute to better fuel efficiency by reducing engine strain, allowing for more efficient combustion and smoother engine operation.
