Dinan Free Flow Axle-Back Exhaust System with Polished Tips for BMW 550i (F10) 2011-2016
Dinan's Free Flow Axle-Back Exhaust is engineered to enhance exhaust flow by reducing back pressure, leading to an increase in power output and delivering a sporty sound that is both refined and aggressive under hard acceleration. Featuring zero drone, this exhaust system strikes the perfect balance between performance and everyday usability. Built from 100% stainless steel, it is designed with exact specifications to ensure a precise fit using the factory hangers, while offering long-lasting corrosion resistance.
A vacuum-controlled butterfly valve is incorporated to optimize exhaust flow at wide-open throttle, maintaining a civilized sound during normal driving conditions while preventing cabin resonance. The system is also lighter than stock and equipped with 3.5" laser-engraved tips, available in polished stainless or ceramic black, for a stylish, high-performance appearance.
