Gibson 08-10 Hummer H3 Alpha 5.3L 3in Cat-Back Single Exhaust - Stainless

If you're looking to get more out of your 2008-2010 Hummer H3 Alpha with the 5.3L engine, this Gibson 3-inch stainless steel cat-back exhaust system is a solid choice. It's designed to bolt directly onto your existing exhaust hangers, making installation straightforward without needing welding or cutting. You can expect a noticeable improvement in sound, with a more aggressive tone during acceleration that quiets down to minimal interior drone at cruising speeds, thanks to its baffled and chambered Superflow™ CFT muffler.

This system is constructed from durable stainless steel, including the mandrel-bent tubing and the polished, slash-cut tip, which resists corrosion and looks sharp exiting straight out the back of your H3. The mandrel bending ensures consistent pipe diameter throughout the system, which helps the engine breathe more freely. Gibson estimates you'll see an average gain of 5-10 horsepower from this improved exhaust flow. Everything you need for a hassle-free, bolt-on installation, including hardware and factory-style hangers, is included.

This Gibson exhaust is backed by a Lifetime Limited Warranty, giving you peace of mind. It's a well-built system that not only enhances the sound and performance of your H3 but also adds a touch of style with its polished stainless tip.
