Dinan Free Flow Axle-Back Exhaust for 2014-2016 BMW M235i - D660-0047-BLK

Give your BMW F22 M235i a louder, sportier exhaust note with the Dinan D660-0047-BLK Free Flow Axle-Back Exhaust. Designed for 2014-2016 BMW M235i and 2015-2016 M235i xDrive models without the M Performance rear valance, this system is constructed from 16-gauge T304 stainless steel and features black ceramic coated 89mm (3.5-inch) laser-engraved exhaust tips. Dinan engineers the system to improve exhaust flow by reducing backpressure while incorporating a Helmholtz chamber to help control unwanted low-RPM drone. Dinan reports gains of up to 6 HP and 5 lb-ft of torque.

The Free Flow exhaust provides a more aggressive tone under acceleration while maintaining a more civilized sound during normal driving. Its corrosion-resistant stainless steel construction is built to use the factory brackets and hangers for factory-style mounting, while the black ceramic tips provide a more aggressive rear appearance.
