The Roush dual cat-back exhaust kit for 2005–2009 Mustang GT and GT500 with factory rear fascia increases flow and yields a deeper, aggressive tone while minimizing in-cabin drone. Constructed with 2.5-inch stainless tubing and mandrel bends for consistent flow, it features polished 4-inch 304 stainless tips embossed with the ROUSH logo. The CNC-bent system improves horsepower and torque over the stock exhaust through higher flow.
