The Gibson single-side cat-back exhaust for 2003–2005 Lincoln Aviator Base 4.6L is a stainless cat-back that exits straight out the back and offers improved low-end power and a deeper exhaust tone. It bolts on using factory-style hangers and mandrel-bent tubing, and includes a baffled Superflow CFT muffler to limit interior drone while delivering an aggressive sound. Polished round slash-cut tip and lifetime limited warranty are included.
