BMW 330i Performance Exhaust - Dinan - Axle Back, Free Flow - Black - 2016–2020. A precision-engineered axle-back that improves flow and delivers a refined, sporty tone with ceramic black tips.

Dinan’s free flow design reduces back pressure for measurable gains while drone-abatement technology helps keep the cabin composed. Built from 100% 16‑gauge 304 stainless steel, it resists corrosion for years. Twin 76 mm (3") laser‑engraved ceramic black tips add a purposeful finish. Installation is a straightforward bolt-on with included hardware, using factory brackets and hangers. Expect gains of +4 hp and +3 lb‑ft at 6600 rpm and a character that is calm on cruise yet pleasantly assertive under throttle. The factory computer‑controlled exhaust valve is removed for a consistent, engaging sound.
