Gibson 03-06 Hummer H2 Base 6.0L 3in Cat-Back Single Exhaust - Aluminized

Gibson is known for making reliable exhaust systems that you can trust, and this cat-back system for your 2003-2006 Hummer H2 is no exception. If you're looking to give your 6.0L H2 a more aggressive sound and a bit more power, this is a solid option. It's designed to bolt right on, making installation straightforward without needing to cut or weld anything, and it exits straight out the back with a polished stainless steel tip for a clean look.

This system uses aluminized, mandrel-bent tubing, which helps maintain consistent exhaust flow. Inside, the Superflow™ CFT muffler is baffled and chambered, engineered to give you an aggressive sound outside the vehicle while minimizing interior drone. You can expect an average gain of 5-10 horsepower from this setup. Gibson backs this exhaust with a Lifetime Limited Warranty, so you can be confident in its durability.

Everything you need for a hassle-free, bolt-on installation is included, along with factory-style hangers. This system is designed to fit your Hummer H2 perfectly, giving you a professional look and improved performance.
