Dinan Free Flow Axle-Back Exhaust System with Black Tips for BMW M235I (F22) 2014-2016
Special Note: For vehicles WITHOUT the M-Performance rear valance
Dinan engineers have developed the Free Flow Axle-Back Exhaust for the F22 BMW M235i to enhance exhaust flow by minimizing back pressure, resulting in an increase in power output and delivering a sporty sound that is both refined at lower speeds and aggressive under hard acceleration. The system incorporates a Helmholtz chamber design, which significantly reduces unwanted resonance, or "drone," at lower RPMs, ensuring a more comfortable cabin experience.
Constructed from 100% 16-gauge 304 stainless steel, the exhaust is built to exact specifications for a precise fit, utilizing the factory hangers. This durable construction guarantees corrosion resistance and long-lasting performance. The system also features twin 89mm (3.5") laser-engraved tips, available in polished stainless or ceramic black, providing a tasteful and high-performance appearance.
