Dinan Free Flow Axle-Back Exhaust for 2017-2020 BMW 330i/430i - D660-0069-BLK

Give your BMW 330i or 430i a deeper, sportier exhaust note with the Dinan D660-0069-BLK Free Flow Axle-Back Exhaust. Designed for select 2017-2020 BMW 330i and 430i applications across the F30, F31, F32, F33, and F36 chassis families, this performance exhaust is constructed from 16-gauge T304 stainless steel and features twin 76mm (3-inch) black ceramic coated, laser-engraved exhaust tips. Dinan reports maximum gains of 4 HP and 3 lb-ft of torque at 6,600 RPM while engineering the system to improve exhaust flow and reduce unwanted low-RPM cabin drone.

The Dinan Free Flow system provides a louder, more aggressive exhaust character under acceleration while maintaining a more refined sound during normal driving. Its stainless steel construction is designed for corrosion resistance, and the system uses factory brackets and hangers with included mounting hardware for straightforward installation. The factory computer-controlled exhaust valve is eliminated with this axle-back system.
