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

Gibson is known for making exhaust systems you can rely on for solid performance. This cat-back system is built for your 2006-2010 Hummer H3 with the 3.7L engine. It's designed to replace your factory exhaust from the catalytic converter back, giving your truck a more aggressive sound and improved flow.

This exhaust uses a baffled and chambered muffler that's designed to minimize interior drone while still giving you that satisfying exhaust note. The tubing is made from aluminized steel, which holds up well, and it's mandrel-bent to keep the pipe diameter consistent for better airflow. It exits straight out the back and includes a polished stainless steel tip with a slash-cut design for a clean look. Installation is straightforward thanks to the bolt-on design and the inclusion of factory-style hangers and hardware.

You can expect to see an average gain of 5-10 horsepower with this system. Gibson backs this exhaust with a Lifetime Limited Warranty, so you can be confident in its durability.
