Dinan Free Flow Axle-Back Exhaust System with Polished Tips for BMW 330i / 430i 2016-2020
Special Note: Has not yet been tested with the M-aerodynamic rear bumper so fitment is not guaranteed on that application.
Dinan's Free Flow Axle-Back Exhaust System for the BMW 330i/430i is designed to enhance performance by reducing back pressure, which increases exhaust flow and results in +4 HP and +3 lb-ft of torque at 6600 RPM. This exhaust system provides a sporty sound that is aggressive under hard acceleration but remains civilized for daily driving. Drone abatement technology ensures minimal cabin resonance, making it ideal for those who want a high-performance sound without intrusive noise.
The system features a simple bolt-on installation using the factory hangers and mounting hardware. It is constructed from 100% 16-gauge 304 stainless steel, which resists corrosion for long-term durability. The exhaust gases exit through twin 3" (76mm) polished or ceramic black laser-engraved tips, offering a sleek, high-performance aesthetic.
