The Gibson aluminized cat‑back single exhaust for 2005–2008 Dodge Durango SXT 4.7L is a popular direct‑fit upgrade that exits straight out the back and finishes with a polished stainless tip. Built to deliver reliable gains—typically around 5–10 horsepower—the system uses mandrel‑bent tubing and a baffled muffler to balance an aggressive sound with minimal interior drone. Includes hardware and hangers for a bolt‑on installation.
