Dinan Free Flow Axle-Back Exhaust System with Black Tips for BMW F22 230i 2017-2021
Dinan engineers crafted the BMW F22 230i Free Flow Axle-Back Exhaust to enhance exhaust flow, reducing back pressure and improving power output while delivering a sporty, aggressive sound under hard acceleration. This exhaust system strikes the perfect balance between a refined tone during regular driving and a more assertive, throaty note when pushed harder. To maintain cabin comfort, Dinan integrated drone abatement technologies to minimize low-RPM resonance, allowing for an intimate driving experience without excessive cabin noise.
Designed for easy installation, the exhaust system utilizes a simple bolt-on setup with mounting hardware included. It’s constructed from 16-gauge 304 stainless steel, ensuring durability and long-term corrosion resistance. The system is available with twin 3" ceramic black or polished exhaust tips, laser engraved for a sleek, high-performance look. The exhaust yields a modest but noticeable performance increase, with up to 4 horsepower and 3 ft-lbs of torque gained at 6600 RPM.
Notably, the factory computer-controlled exhaust valve is eliminated with this system, simplifying the design while maintaining a sporty sound profile throughout the rev range.
