Gibson 03-04 Nissan Xterra SE 3.3L 2.25in Cat-Back Single Exhaust - Aluminized

When you're looking to get more out of your 2003-2004 Nissan Xterra SE, this Gibson cat-back exhaust system is a solid option. It's designed to bolt right onto your 3.3L engine, replacing the factory exhaust from the catalytic converter back. You'll get a single exhaust that exits behind the rear tire, giving your Xterra a cleaner look and a more aggressive sound when you step on the gas.

This system uses aluminized, mandrel-bent tubing for smooth exhaust flow, which Gibson says can lead to an average gain of 10-15 horsepower and 15-20 lb-ft of torque, especially noticeable in the low-end RPM range. The baffled and chambered muffler is engineered to provide a more aggressive sound outside the vehicle while keeping interior cabin noise and drone to a minimum. It also includes polished stainless steel slash-cut tips for a clean finish.

Installation is straightforward thanks to the included hardware and factory-style hangers, meaning no welding is required. Gibson backs this system with a lifetime limited warranty.
