Dinan Free Flow Axle-Back Exhaust for 2011-2016 BMW 535i F10 - D660-0051

Give your 2011-2016 BMW F10 535i or 535i xDrive a louder, sportier exhaust note with the Dinan D660-0051 Free Flow Axle-Back Exhaust. Constructed from 16-gauge T304 stainless steel, this performance exhaust is engineered to improve exhaust flow by reducing backpressure while incorporating a Helmholtz chamber to help control low-RPM resonance and drone. This D660-0051 version features polished 89mm (3.5-inch) laser-engraved exhaust tips, and Dinan reports gains of up to 6 HP and 5 lb-ft of torque at 6,600 RPM.

The Dinan Free Flow system is designed to provide a more aggressive sound under acceleration while maintaining a more refined cabin experience during normal driving. It uses the factory brackets and hangers for factory-style mounting and is constructed from corrosion-resistant T304 stainless steel. Unlike the stock exhaust configuration, the Dinan system eliminates the factory computer-controlled exhaust valve.
