This is a new high-quality BMW Dinan M5 exhaust. It only works for BMW M5 E60(2006~2010). BMW Dinan M5 exhaust System provides maximum flow characteristics for optimum power gains while producing a civilized, yet very sporty exhaust note that is appropriately aggressive at wide open throttle. And there's none of that irritating low rpm ''drone'' that is common with so many aftermarket mufflers. The mufflers are manufactured from 100% 304 stainless steel inside and out for maximum resistance to corrosion and nearly a 30% reduction in weight, eliminating over 20 lbs. Finished with four 3.5'' diameter black tips to give the car a more aggressive look. Utilizing the factory brackets and hangers, the Dinan exhaust mounts in a factory-like fashion for a perfect fit and clean installation. The price of the item is only $1800. please feel free to contact me if you are interested in this exhaust.
