BMW 430i Performance Exhaust - Dinan - Freeflow Axleback - Polished - 2017–2020. Purpose-built for the 430i, this axle-back adds a crisp, sporty voice while delivering measurable performance gains.

Engineered by Dinan to reduce back pressure and improve exhaust flow, the system produces up to +4 hp and +3 lb-ft at 6600 rpm. Drone abatement keeps the cabin composed at low RPM, while the note turns pleasantly aggressive under hard acceleration. Built from 100% 16-gauge 304 stainless steel for durability and corrosion resistance, it sports twin 76 mm polished, laser-engraved tips. The straightforward bolt-on design uses factory brackets and hangers, includes mounting hardware, and removes the factory computer-controlled exhaust valve.
