Gibson 08-10 Hummer H3 Alpha 5.3L 2.5in Cat-Back Dual Extreme Exhaust - Stainless

If you're looking to give your 2008-2010 Hummer H3 Alpha with the 5.3L engine a more aggressive sound and improved performance, this Gibson 2.5-inch cat-back exhaust system is a solid option. It's designed to exit behind the rear tires at an aggressive angle, giving your truck a bold street look that matches its enhanced exhaust note. This system is built for those who want to push their truck's capabilities further.

The heart of this system is Gibson's Superflow CFT muffler, which uses baffles and chambers instead of internal packing to create a mean performance sound. It's dyno-tuned and tested to help you experience noticeable gains in horsepower, typically in the range of 15-20 HP, without creating excessive interior drone. The tubing is made from stainless steel and is mandrel-bent to ensure smooth airflow, complementing the polished stainless steel slash-cut tips. Everything you need for installation, including all hardware and factory-style hangers, is included, making it a hassle-free bolt-on process with no welding required.

This Gibson exhaust system is backed by a Lifetime Limited Warranty, reflecting its well-built construction. It's a complete cat-back solution designed for easy installation and a significant upgrade in both sound and performance for your Hummer H3 Alpha.
