Dinan Free Flow Axle-Back Exhaust System with Polished Tips for BMW F22 230i 2017-2021
Dinan engineered the BMW F22 230i Free Flow Axle-Back Exhaust to enhance exhaust flow by reducing back pressure, resulting in improved power and a more dynamic, sporty sound. Designed for a perfect balance, the system produces a refined tone during regular driving while delivering an aggressive growl under hard acceleration. To ensure cabin comfort, drone abatement technologies are employed to minimize low-RPM resonance. The exhaust system is built from 100% 16-gauge 304 stainless steel for long-term durability and corrosion resistance, with a straightforward bolt-on installation. The twin 3" ceramic black or polished laser-engraved exhaust tips add a tasteful, high-performance aesthetic while delivering performance gains of up to 4 horsepower and 3 ft-lbs of torque.
