Gibson 2005 Nissan Xterra S 4.0L 2.5in Cat-Back Single Exhaust - Stainless

If you're looking to get more out of your 2005-2014 Nissan Xterra, especially when it comes to hauling, climbing hills, or just everyday driving, this Gibson cat-back exhaust system is a solid option. It's designed to help your 4.0L engine breathe a little easier, which can make a noticeable difference in how your Xterra performs, particularly at lower RPMs where you need that extra push.

Gibson built this system using mandrel-bent stainless steel tubing, which means the pipe diameter stays consistent throughout the bends, allowing for better exhaust flow compared to stock. The Superflow™ muffler is baffled and chambered, not packed, which helps reduce interior drone while still giving you a more aggressive sound outside the vehicle. Dyno tests show this system can add around 10-15 horsepower and 15-20 lb-ft of torque, most of which shows up between 1800 and 3000 RPM. The exhaust exits behind the rear tire with a polished stainless steel slash-cut tip for a clean look.

Installation is designed to be straightforward, using factory-style hangers and including all the necessary hardware, so no welding is required. This makes it a bolt-on upgrade that you can often do yourself or have a shop handle without much fuss. Gibson backs this system with a lifetime limited warranty, giving you peace of mind with your investment.
