Gibson 07-10 Hummer H3 Base 3.7L 2.5in Cat-Back Dual Extreme Exhaust - Stainless

Gibson is known for making well-built exhaust systems that give your vehicle a distinct sound and improved performance. For the Hummer H3 owner looking to really push their truck's capabilities, this Dual Extreme cat-back system is designed to do just that. It replaces your factory exhaust from the catalytic converter back, exiting aggressively behind the rear tires with a dual slash-cut tip setup that looks as mean as it sounds.

This system uses a Superflow™ CFT muffler, which is baffled and chambered without internal packing, to produce an aggressive performance tone while minimizing interior drone. The tubing is made from stainless steel and is mandrel-bent to ensure smooth exhaust flow, which Gibson dyno-tunes and tests to achieve noticeable street performance gains, typically around 15-20 horsepower. The tips are polished stainless steel with a slash-cut design, adding a bold street look to your H3. Everything you need for installation is included, and it's designed as a hassle-free bolt-on system, meaning no welding is required.

This cat-back exhaust system is a solid choice for those wanting to extract more performance and a more aggressive sound from their Hummer H3. It comes with all the necessary hardware and factory-style hangers for a straightforward installation. Gibson backs this system with a Lifetime Limited Warranty, giving you confidence in its durability.
