Dinan Free Flow Axle-Back Exhaust for BMW | E6X | 535i/550i (03/2007+) - (NLA)

Part# D660-0020

The Dinan sport muffler is designed to compliment the engine sound and not overpower the driver and passengers with harsh tones. Dinan engineers their exhausts to sound great and be a natural fit to the character of the car as well as produce more power and torque. Dual 3.0" stainless tips engraved with the Dinan logo fill out the rear valence. Annoying highway drone has also been engineered out of the system. Dinan uses only 304 stainless steel in their systems for the maximum corrosion protection. This system replaces the factory rear mufflers at a pre-determined cut point on the stock exhaust, which makes for an easy installation and you can reinstall your original mufflers using factory hardware. Detailed installation instructions are included.

Note: Note applicable for 550i (E60) 1/2006 to 2/2007.
