Product Details
Gibson is known for making exhaust systems that give vehicles a more aggressive sound and improved performance, and this Dual Extreme Cat-Back system for your 2009 Hummer H2 is no exception. If you're looking to really uncork the sound and power of your 6.2L H2, this system is designed to take it to the next level. It's built to exit behind the rear tires at an aggressive angle, giving your truck a bold street look that matches its powerful exhaust tone.
This system uses a Superflow™ CFT muffler with a baffled/chambered design, meaning it doesn't rely on internal packing to control sound. This design is dyno-tuned and tested to deliver noticeable street performance gains, with many users experiencing an average of 15-20 horsepower. The tubing is made from stainless steel and is mandrel-bent to ensure smooth airflow, while the polished stainless steel slash-cut tips add a finishing touch. Gibson has also worked to minimize interior drone, so you can enjoy the aggressive sound without it becoming overwhelming on the highway.
Installation is straightforward thanks to the bolt-on design, which includes all the necessary hardware and factory-style hangers, so no welding is required. This system is backed by Gibson's Lifetime Limited Warranty, giving you peace of mind with your purchase.
