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

Give your 2011-2016 BMW F10 535i or 535i xDrive a louder, sportier exhaust note with the Dinan D660-0051-BLK 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 unwanted low-RPM resonance and drone. This D660-0051-BLK version is finished with black ceramic coated, laser-engraved exhaust tips, and Dinan reports gains of up to 6 HP and 5 lb-ft of torque at 6,600 RPM.

The system is built to use the factory brackets and hangers for factory-style mounting while providing a more aggressive exhaust character under acceleration. Unlike the factory system, the Dinan axle-back eliminates the factory computer-controlled exhaust valve. Corrosion-resistant T304 stainless steel construction and the black ceramic coated tip finish complete the performance-focused design.
