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

This Gibson cat-back exhaust system is built with 2.5-inch mandrel-bent stainless steel tubing, designed specifically for your 2006-2010 Hummer H3 with the 3.7L engine. The dual split rear exit configuration gives your truck a more aggressive look and a throaty exhaust note that's noticeable, especially under load. It's a solid choice if you're looking to change up the sound and flow of your H3's exhaust system.

The system features a Superflow™ muffler that uses baffling and chambers instead of internal packing, which helps minimize interior drone while still producing a more aggressive sound outside the vehicle. This design also contributes to reduced backpressure, potentially leading to improved torque and horsepower. The polished stainless steel slash-cut tips exit straight out the back, offering a clean, finished look that works well with most factory bumpers and trailer hitches.

Installation is designed to be straightforward with a bolt-on process that doesn't require welding, making it a hassle-free upgrade. Gibson backs this exhaust system with a Lifetime Limited Warranty, giving you confidence in its durability. If you're looking to give your Hummer H3 a more distinct sound and appearance, this dual split cat-back system is a well-built option.
