Neuspeed Cat Back Exhaust For 2.7T S4

About the exhaust: (NEUSPEED's all-stainless catalyst-back exhaust system rivals the best that Europe has to offer! Our latest generation of exhausts use aerospace quality T304 stainless metric-sized tubing for maximum flow. Two low restriction mufflers at the rear are carefully designed to reduce weight and meet State noise restriction standards. Mandrel bends, precise fit flanges, mounting hangers, gasket(s) and hardware are standard on every NEUSPEED exhaust system)
