Eisenmann Axle-Back Exhaust for BMW G2x M340i/M440i (OPF In Place)
Unlock a new level of performance and sound with the Eisenmann Axle-Back Exhaust for the BMW G2x M340i/M440i. Engineered for enthusiasts who demand both power and acoustic perfection, this high-performance exhaust system offers a significant upgrade over the factory setup while maintaining the essential OPF (Otto Particulate Filter) for those who prefer to keep their emissions intact. Available in a few different finishes and tip designs.
Please note: this is a dual-valve system, while the original is a single-valve system. So one additional motor (available at BMW) is required to operate the exhaust flaps.
Key Features:
-
Axle-Back Design: The Eisenmann Axle-Back exhaust replaces your stock rear mufflers, providing a deep, aggressive exhaust note without affecting the OPF. Enjoy a sportier sound that enhances your driving experience, with a refined tone at cruising speeds and a thrilling growl under hard acceleration.
-
Perfect Fitment: Designed specifically for the BMW G2x M340i/M440i, the Eisenmann system delivers precise fitment that’s easy to install.
-
Optimized Performance: While the OPF remains in place with the axle-back system, you’ll still notice improvements in exhaust flow and overall engine response, leading to more power and a faster throttle response.
-
Customization Options: For those seeking even more performance, the Eisenmann Axle-Back can be paired with an Akrapovic or Evolution M midpipe for an OPF delete. This combination unlocks even greater exhaust flow, increasing horsepower and torque while giving your BMW a richer, more aggressive exhaust note. (Note: Cars built after June 2020 may require an ECU unlock to fully integrate an OPF delete midpipe.)
-
Premium Build Quality: Crafted from high-quality stainless steel, the Eisenmann exhaust is designed to resist corrosion, ensuring durability and longevity. The sleek, polished finish adds an elegant touch to the rear of your BMW, while the design features perfectly welded seams and top-tier materials.
