Active Autowerke M340i/M440i Midpipe (Part #11-128)

The Active Autowerke M340i/M440i Midpipe is engineered for BMW enthusiasts looking to enhance the auditory experience of their G2X and G3X models. This midpipe is designed specifically for the 2019-2025 BMW M340i and M440i, providing a significant upgrade over the factory setup.

Construction and Design

  • Material: Constructed from high-quality 304 stainless steel, ensuring durability and resistance to corrosion.
  • Sound Profile: Delivers a low, deep exhaust note that enhances the driving experience without being overly aggressive.
  • Fitment Testing: Each unit is test-fitted on our M340i/M440i Exhaust Fixture to ensure compatibility and performance.
  • Custom G2X Brace: Included with the midpipe, this brace provides additional clearance and stability.

Performance Enhancements

By eliminating the resonator from the stock midpipe, this upgrade improves exhaust flow and resonance, resulting in a more pronounced sound that complements both stock and aftermarket exhaust systems. The midpipe is designed to work seamlessly with the factory exhaust, enhancing the overall sound profile.

Installation Notes

  • This midpipe is intended for those who wish to replace their stock midpipe. Installation requires cutting, but all necessary connecting hardware is included.
  • If paired with the Active Rear Exhaust, the entire stock exhaust can be removed without cutting, simplifying the installation process.

Fitment

  • BMW M340i | M440i G2X (2019-2025)

With the Active Autowerke M340i/M440i Midpipe, you can expect a refined balance of sound and performance, making it a worthy addition to your BMW’s exhaust system.
