$1,227.99
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2006-2010 Hummer H3 Base and X models (3.7L).
The Gibson Dual Split Cat-Back Exhaust system is designed for the enthusiast seeking an aggressive, throaty exhaust note and improved performance. By decreasing backpressure, this system helps produce more torque and horsepower, with typical gains averaging between 15-20 horsepower. The included Superflow Muffler features a baffled and chambered design with no internal packing to blow out, ensuring a consistent sound profile and minimal interior drone.
This system is engineered for a hassle-free, bolt-on installation using factory mounting points with no welding required. It is compatible with most aftermarket bumpers, roll pans, and trailer hitches. The aluminized mandrel-bent tubing ensures smooth exhaust flow, while the dual polished stainless steel tips provide a clean, high-performance look.
