Gibson Single Side Cat-Back Stainless Steel Exhaust for 2004-2011 Nissan Armada & Infiniti QX56 (5.6L) - 3in

Fits 2004-2011 Infiniti QX56 and Nissan Armada models (5.6L).

The Gibson Single Side Exhaust system is engineered to provide increased low-end torque and horsepower, specifically between 1,800 and 3,000 RPM. This makes it an ideal upgrade for heavy-duty applications such as towing, hauling, or climbing steep grades. Built from 3-inch mandrel-bent stainless steel tubing, this system ensures consistent exhaust flow without the restrictive bottlenecks found in factory crimp-bent pipes.

At the core of the system is the Superflow™ muffler. Featuring a baffled and chambered design with no internal packing to blow out over time, it delivers a deep, aggressive exterior tone while maintaining a quiet, drone-free experience inside the cabin. Installation is a straightforward bolt-on process using professional-grade hardware and factory-style hangers, requiring no welding or specialized tools. The system is finished with a polished stainless steel slash-cut tip that exits behind the rear passenger-side tire.
