Gibson 04-10 Infiniti QX56 Base 5.6L 3in Cat-Back Single Exhaust - Stainless

Gibson is known for making well-built exhaust systems that improve performance. This particular cat-back system is designed for your 2004-2010 Infiniti QX56, offering a noticeable boost in acceleration, hill climbing, and towing capabilities. It exits behind the rear tire, giving your SUV a cleaner look while still providing an aggressive sound that won't overwhelm your cabin.

This system is constructed from polished stainless steel, including the mandrel-bent tubing and the slash-cut tips, which means it's built to resist corrosion and last for years. The Superflow™ muffler uses a baffled and chambered design, not internal packing, to reduce interior drone while still allowing for maximum torque and horsepower gains, especially in the low-end RPM range where you need it most for towing and passing. Dyno tests show an average increase of 10-15 horsepower and 15-20 lb-ft of torque.

Installation is straightforward thanks to the bolt-on design that uses factory-style hangers and includes all necessary hardware, so no welding is required. Gibson backs this system with a lifetime limited warranty, giving you peace of mind with your purchase.
