The Dinan M5 axle-back 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 theres 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. The four 3.5 in. diameter polished stainless steel tips not only give the car a more aggressive look but also feature Dinan new Cool Tip design that effectively reduces temperatures in order to minimize radiant heat that can effect body work 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 trun
