Dinan Free Flow Axle-Back Exhaust System for BMW 328i / 428i 2012-2016
Dinan engineers have meticulously designed the BMW 328i/428i Free Flow Axle-Back Exhaust to enhance exhaust flow and reduce back pressure, resulting in increased power output and a sporty sound profile that strikes a perfect balance. The system delivers a civilized tone during regular driving but transforms into a pleasantly aggressive roar under hard acceleration. With a focus on driver experience, Dinan's advanced drone abatement technologies significantly minimize low-RPM drone, ensuring a refined cabin environment without excessive noise.
Constructed from 100% 16-gauge 304 stainless steel, this exhaust system is built for durability and resistance to corrosion, promising longevity and performance. The design incorporates twin 70mm (2.75") exhaust tips, available in polished or ceramic black finishes, each laser engraved for a sophisticated high-performance appearance. The installation process is straightforward, using the factory brackets and hangers for a seamless fit. Notably, the factory computer-controlled exhaust valve is eliminated, enhancing the system's efficiency. This exhaust offers a maximum performance gain of 4 horsepower and 3 lb-ft of torque at 6600 RPM, providing an exciting upgrade for your BMW.
