Dinan Free Flow Axle-Back Exhaust System with Black Tips for BMW 335i / 435i 2012-2016
Special Note: Factory computer-controlled exhaust valve is eliminated.
Dinan engineers developed the Free Flow Axle-Back Exhaust for the F30 335i and F32 435i to enhance exhaust flow by reducing back pressure, which results in increased power output and a sporty, refined sound. The exhaust is designed to maintain a civilized tone during normal driving, yet deliver a pleasantly aggressive note under hard acceleration. Dinan's use of a Helmholtz chamber helps to reduce unwanted resonance, or "drone," at lower RPMs for a more enjoyable driving experience.
Constructed from 100% 16-gauge 304 stainless steel, this system is corrosion-resistant and built to last. The exhaust features twin 3.5" laser-engraved exhaust tips available in either polished stainless or ceramic black, giving the car a tasteful and high-performance aesthetic.
The factory computer-controlled exhaust valve has been eliminated to provide a more consistent exhaust sound.
