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

With this Gibson cat-back exhaust system, you're getting a complete setup designed specifically for your 2003-2006 Hummer H2 with the 6.0L engine. This kit includes the exhaust system itself, a polished stainless steel tip, and all the necessary hardware and factory-style hangers to make installation as straightforward as possible. It's a bolt-on system, meaning no welding or cutting is required, leading to a professional look once it's all put together.

The heart of this system is Gibson's Superflow™ CFT muffler, which uses a baffled and chambered design without internal packing. This construction is key to achieving a more aggressive exhaust note outside the vehicle while keeping interior drone to a minimum, so your cabin stays comfortable during everyday driving. The tubing is made from stainless steel and is mandrel-bent to ensure smooth airflow, which helps contribute to the average 5-10 horsepower gains you can expect. The system exits straight out the back and is finished with a polished, round, slash-cut stainless tip.

This Gibson exhaust is built to last, featuring stainless steel construction throughout and backed by a Lifetime Limited Warranty from the manufacturer. If you're looking to give your Hummer H2 a more distinct sound and a bit of an edge in performance, this cat-back system is a solid option.
