Gibson 07-10 Hummer H3 Base 3.7L 2.5in Cat-Back Dual Split Exhaust - Aluminized

This Gibson cat-back exhaust system is built with aluminized steel tubing, featuring a 2.5-inch diameter that splits into dual exits out the back. It's designed to bolt directly onto your 2006-2010 Hummer H3 with the 3.7L engine, making installation straightforward without needing any welding. The system includes polished stainless steel slash-cut tips for a clean look.

The Superflow™ muffler at the heart of this system uses a baffled and chambered design without internal packing. This approach helps reduce backpressure, which can lead to improved torque and horsepower, often in the range of 15-20 HP. While it produces an aggressive, throaty sound, Gibson has worked to minimize interior drone, so you can enjoy the rumble without it becoming overwhelming on the highway, even under towing conditions.

This exhaust is a solid option if you're looking to change the sound and performance of your H3. It's designed to work with most bumpers, roll pans, and trailer hitches. Gibson backs this system with a Lifetime Limited Warranty, giving you peace of mind with your purchase.
