Dinan D660-0009A Free Flow Axle-Back Exhaust - Compatible with 2006-2010 BMW M5
Stainless Steel - Polished Tips - E60
The four 3.5 in. diameter polished, or ceramic black, stainless steel tips not only give the car a more aggressive look but also feature Dinan's new Cool Tip design that effectively reduces temperatures in order to minimize radiant heat that can affect bodywork over time, as well as avoid discoloration of the tips themselves. The Cool Tips also avoid the possibility of a nasty burn while loading items in the trunk. Employing the principle of rarefaction, the design features an inner and outer tip with a vent at the base. When a positive pressure wave travels to the end of an open pipe and is ultimately expelled into the atmosphere, a rarefaction or momentary drop in the density of the surrounding air is created behind it. This momentary drop in the density of the air surrounding the pipe's exit creates a vacuum, pulling the air from the surrounding area to fill the void. The vent at the base of each outer tip then enables air to be drawn in effectively cooling the tips.
Utilizing the factory brackets and hangers the Dinan exhaust mounts in a factory-like fashion for a perfect fit and clean installation.
