Description
The Dinan Free Flow Stainless Exhaust System (part number D660-0050-BLK; Summit Racing part number DNN-D660-0050BLK, UPC 813725021874) is a rear axle-back system with a split-rear exit. Dinan describes its free-flow systems as precision-engineered for power gains and a civilized, sporty exhaust note that becomes appropriately aggressive at wide-open throttle, without the irritating low-rpm drone common to many aftermarket mufflers.
The system is made from 304 stainless steel inside and out. Dinan states that this construction offers corrosion resistance and reduces weight by 30 percent. It uses OE brackets and hangers for factory-like mounting. Confirm the application for your vehicle before ordering; no specific vehicle fitment is listed here.
